Even if tsubomi doesn't win, seeing ueno and tsubomi's relationship grow slowly until they finally become friends is definitely my favorite part of the story. Close second being kanako's development and talks with ueno.

Still bummed tsubomi ain't the one but great story anyway.

One year anniversary of this manga with zero hiatus throughout! Author said the story might conclude next year around this time.


As we are getting closer to the ending, the author is already beginning plans for his next work. I'm going to be sad once the manga ends.

I'm curious about what he's planning to do next. Before this manga, he did a few one-shots. Funny enough, one of the characters in the one-shots looks similar to Chisaki, from her to hairstyle to her snaggletooth, lol.

Chapter 63 is out and free to read. This is a pretty good and emotional chapter. Read the chapter and the summary to understand why.


The chapter starts off with a brief flashback with Ueno finding out the bully trio's gym clothes in the classroom and getting aroused (this should dispel any theories that it wasn't Ueno's fault that he was holding the bullies' gym clothes). This is why Ueno tells Tsubomi in present time that he blames himself as the reason why he was bullied in the first place. A speechless Tsubomi asked Ueno why he could say something like that. Ueno replied that he doesn't know, but he thinks it's a nice opportunity for him and Tsubomi to become proper friends. Hearing that made Tsubomi feel incredibly guilty, which caused her to run away from Ueno. Ueno chased after a crying Tsubomi, telling her to come back to the tennis club tomorrow, and to stop running. When she didn't stop, Ueno yelled to Tsubomi that they can start over and become proper friends as he doesn't want to their new friendship to end like that. Tsubomi stopped and fully broke down in tears, apologizing repeatedly for her actions to Ueno.

In the next scene, Tsubomi asked Ueno about whether or not they can do erotic things anymore which Ueno confirms that they can't since he is dating Moka. This caused Tsubomi to pout, lol.

When Ueno was about to walk home, Tsubomi stopped him, saying...

she wants to 'practice' with Ueno, one last time.

( SAY YES, UENO!!!! SAY YES, UENO!!!! SAY YES, UENO!!!! SAY YES, UENO!!!! SAY YES, UENO!!!! SAY YES, UENO!!!! SAY YES, UENO!!!! SAY YES, UENO!!!! SAY YES, UENO!!!! SAY YES, UENO!!!! SAY YES, UENO!!!!)

The art is getting better. This chapter have the best art in the series so far. Tsubomi's character growth is one of the best parts of this series. I love how she broke down and cried and how Ueno was willing to start over to become proper friends with each other. Overall, this is a beautiful and emotional chapter...

...well, until the final scene though. lol. Wow, what a troubling request. I mean, obviously Ueno shouldn't cheat on Moka, especially this early into the relationship but.....as a reader, I don't want Ueno to miss out on the opportunity to do intimacy practice with Tsubomi one last time. Tsubomi and Ueno will definitely feel absolutely guilty afterwards, but as long as the sex scene is excellent, I will say it will be worth it. I don't want the erotic/femdom scenes to dry up this soon.

But, I can't WAIT for the next chapter. Will Tsubomi (and Ueno) finally lose their virginity within the next two chapters?!?

Hopefully he says no, Ueno has already moved on from the bullies, with the story coming to a close his happiness is guaranteed

I got the feeling the manga is heading towards the conclusion in the next 10 or so chapters. This will be the final Tsubomi "encounter", then wrap things up with Kanako next, and then finally the choice between Moka and Chisaki (likely the latter)

I thought this manga is going to end around Fall 2026, but it does feel like it’s going to end sooner than what I expected.

Chapter 64 is out and free to read. So will Ueno cheat on Moka this early into the relationship?! Read the chapter and the summary to find out.

Tsubomi told Ueno that she never done insertion before and she wants to practice with Ueno one last time before they become normal friends. Ueno was initially surprised before rejecting Tsubomi, saying that he can't cheat on Moka. In a humorous scene, Tsubomi became embarrassed and started to argue with Ueno about their decency before telling him that doing dirty things with Ueno was fun. According to Ueno, she wasn't exact wrong with that remark...

Tsubomi conceded and told Ueno that she won't request Ueno to do anything dirty for the sake of Moka, relieving Ueno. Later on, Ueno was laying on bed, pondering about the future outcomes with Chisaki and Kanako. Ueno fell asleep and had a wet dream of having a foursome with the bully trio. When Ueno woke up and checked his pants, Ueno felt completely ashamed of what he saw.

Later on, Ueno went to the tennis club. Tsubomi tried to say hello, but Ueno kept avoiding her until Tsubomi asked Ueno why he is doing that. Tsubomi mentioned that until they get used to being normal friends, they should stop meeting together alone and they should only conversate in group settings only. After all, Tsubomi is not doing this just for Ueno, but also for Moka's sake. A relieved Ueno thanks for Tsubomi for selflessness and the chapter ends with the two talking to their friend groups.

(Incredible maturity)

Great chapter. It was too early to cheat on Moka and I'm glad Ueno was resolute in rejecting Tsubomi's request (unfortunately, lol). I'm also pleased to see Tsubomi taking a mature approach of setting boundaries between her and Ueno until they get used to being normal friends. Incredible to see a mature approach from Tsubomi.

Ueno's wet dreams are one way to have erotic scenes with the bully trio without him cheating on Moka. He had those lewd foursome thoughts before in the beginning of this series, and now, they're manifesting again. Those wet dreams should give Ueno pressure to relapse if he doesn't do anything to stop it.

With Kanako's turn next, I wonder what she will do with Ueno now?

It's a good outcome, next, let's dispose of the other two bully girls and the story is complete

God damnit, Chisaki making a college band would've made for an amazing story angle. She has that Maki Gamou energy and charm that's just so engaging.

Too bad she's a sadistic abuser.

I'm calling it now, Mikako Komatsu as the voice of Chisaki, Tomori Kusunoki as Kanako, Aina Suzuki as Tsubomi, heck let Sumipe voice Moka because she can voice anyone.

Chisaki could make a splash in the music industry if the law field doesn't pan out for her, lol.

Chapter 65 is out and free to read. Chisaki and Moka are hanging out this chapter. I wonder what's on their mind? Reading the chapter and the summary might answer that question.

The chapter starts off with Chisaki and Moka going to a rock n' roll concert together. Chisaki invited her to attend. Moka was initially nervous as this was her first concert but ultimately the duo had a great time watching the concert together. After the concert, the duo was walking home when Moka asked Chisaki if she played the guitar or the bass. Chisaki admitted she only played guitar for only a little bit, but it was enough for Moka to encourage Chisaki to head to the nearest music shop for Moka to see Chisaki actually play the guitar!

After that, Chisaki and Moka started to walk home again. Moka asked Chisaki some questions about how she learned the guitar and as Chisaki started to explain it an emo way, she became embarrassed, lol. Chisaki lit up another cigarette and told Moka that once Moka turns 20, they will take a smoke together (maybe...). The tone of the story then switched suddenly when Moka asked Chisaki about her true relationship with Ueno. Chisaki seemingly gave Moka a non-serious answer that Ueno is her slave, but the answer confirmed to Moka that Chisaki was actually Ueno's bully. Moka doesn't look too surprised as she did notice the hints about Ueno's relationship with Chisaki wasn't as friendly as it seems...

Moka then pleaded to Chisaki to explain Chisaki's true character. Not just for the sake of Moka's relationship with Ueno but for the fate of the relationship between her and Chisaki. Chisaki walked away, telling Moka to ask Ueno for the answer instead, leaving behind a stunned Moka.

(R.I.P Chisaki-Moka's friendship...)

Time then progressed to the start of a new semester. The chapter ends with Ueno and Moka having a fun conversation while a melancholic Kanako watches them from afar...

An unexpected friendship over? What a sad situation....

mQrhNXW.png


Well, after Moka had this thought above in chapter 27, I knew it was only a matter of time before she confronted Chisaki about her past relationship with Ueno. Even then, Moka only partially understands the relationship and ultimately, it will be up to Ueno to tell Moka the complete truth. While I don't expect Moka to demand Ueno the truth yet it, I do expect it will start to gnaw at her mind.

Now finally, we're getting Kanako chapters and I'm very interested on what she will do next. While Kanako may be relieved that Ueno is dating Moka, she does like tormenting him. I wonder how Kanako will approach the situation and how Ueno will respond to the most intimidating bully out of the bully trio...

Can't wait for the next batch of chapters.

Volume 6 will be out on February 2026.

Looks like the release date for volume 6 has been confirmed. No cover yet but it probably will be Tsubomi on the cover again at least. EDIT: It will be Tsubomi and Moka doing tennis. Volume 6 will also probably stop at chapter 50.

I wonder what bonus content will be in this volume, if any? A good idea is Tsubomi using the toys she brought home from her last practice play with Ueno, lol.

Chapter 66 is out and free to read. Looks like Chisaki and Kanako is having a serious conversation throughout the chapter. What's on their minds? Just like last chapter, reading the chapter and the summary might answer that question.



The story starts off at the college campus. While Ueno was talking to his buddies, Chisaki was smoking her cigarette waiting for Kanako & Tsubomi to arrive. When the duo arrived, Kanako & Tsubomi gave Chisaki some grief about her smoking on campus, lol. The bully trio then ran into Moka and Ueno. Ueno looked startled seeing the bully trio while Moka acted cordial as she engaged with small talk with them. Chisaki then stared at Ueno, but Ueno couldn't bring himself to make eye contact at her.

The group then splintered off, with Tsubomi hanging out with Moka & the rest of the girls from the tennis group for dinner while Kanako & Chisaki walk somewhere else. Chisaki & Kanako made a note how Tsubomi is making friends from the tennis club, a club which Chisaki doesn't seem to like.

The conversation then pivoted into Kanako asking for Chisaki's opinion of Ueno and the situation of him dating Moka. Chisaki believes a nice girl like Moka is too good for Ueno. That's when Kanako made a surprising revelation that she's done bullying Ueno as Moka is too precious for Kanako to continue doing that. EDIT: Kanako was talking about Chaski. My mistake. Kanako believes that Chisaki has some sort of attachment to Ueno which Chisaki initially denies. Chisaki claims that she doesn't like Ueno, but she admitted that she stopped understanding what she really feels about him.

Hearing that surprised Kanako, as it felt out of character for Chisaki to admit any sort of confliction. Kanako also ponders if Ueno makes Chisaki the happiest when he's around. Chisaki then suddenly apologized to Kanako for not being able to respond to her romantic feelings as Chisaki feels content by having the important people in her life happy. Chisaki feels she has trouble expressing that type of endearment to Kanako. Kanako couldn't believe that Chisaki is apologizing as Kanako felt like she didn't try harder to win Chisaki's affection.

Kanako then made a comment about self-reflection which puzzled Chisaki. Kanako followed up by asking Chisaki about her true feelings as Kanako believes Chisaki wants to keep Ueno all by herself because she's dependent on him. Chisaki wondered about that, admitting that she has been wavering in her thoughts recently. The chapter ends with Chisaki wanting to talk to Ueno, to settle things once and for all.

Talk about a mature chapter. That's what I like about Kanako. She does play a strong role in helping Ueno and Chisaki think critically about themselves and the relationship between each other. That is not simple bullying that is going, but a more complex relationship brewing underneath. Now, Chisaki claims repeatedly throughout the story she doesn't like Ueno, but in this chapter, she doesn't deny that she's dependent on Ueno. After all, he still is the only person to make her feel aroused. If Chisaki can break the dependence, it will be a lot easier for her to leave Ueno in peace and for him to break his programming.

I will also say that I am surprised to see Kanako to have some level of endearment to Moka since they hardly interact with each at all throughout this story. If chapter 44-46 is indeed the last time we will see femdom content from Kanako, I admit I will be disappointed since I do enjoy her scenes the most and Kanako is my favorite character in the series.* However, I do commend Kanako for denouncing her bullying ways without having Ueno resisting her first. I hope Kanako tells that to Ueno next chapter. It will give him some relief to have another former bully from the trio supporting him and his relationship with Moka.


EDIT: Again, Kanako was talking about Chisaki feelings of Moka, not herself*.

Holy shit, Chisaki being mature about all of this? At least they all know what they did to Ueno was reprehensible, so the current status quo is surprisingly the best possible outcome for all of them.

Though I honestly want the bully trio to receive some sort of comeuppance. Yes, I'm including our favorite Tsubomi!

Honestly the part of the series that originally hooked me seems to be over, but I am happy to finish this series since I do enjoy the characters. It does seem like it could be wrapped up with any kind of real drama happening which I did not expect, especially with how som manga tends to play out, but if Chisaki is able to cut ties with Ueno and him and Moka can live happily ever after l, then that is great. Though with how Ueno and Moka were in their past relationships, I do think we need to see how their sex life goes as being able to have a healthy one between them after being in such unhealthy ones I feel is important to explore. I guess we won't see a final exchange with Ueno and Kanako like with Tsubomi, but that's prolly for the best since she was always the most emotionally distant one of the three
