● Flashback to Kazuki's memories before the time leap. A new heroine joins Amada's harem, a transfer student who's secretly a Vtuber with over 1 million subs, Hitsujitani Miwa (Hanatori Miyabi). They get close after Amada helps solve a stalker problem Miwa's dealing with, roping in all the guys in class to help catch the guy. But the stalker issue doesn't end with just catching him, it spirals into figuring out who leaked Miwa's address and personal info to the stalker in the first place. After digging around with some "evidence," it points to Kitami Sae, a girl from another class who's also a Vtuber but only has 50 subs, supposedly out of jealousy toward Miwa (Miyabi). Because of the accusation, Sae ends up leaving school. Sae was the only real female friend Hidaka Mikoto had. Kazuki still remembers the cold, sad look on Hidaka's face after losing Sae.
★ Timeline after the time leap.
After what happened in volume 1, Amada stops coming to school. His heroines, all burned by him now, join Kazuki's circle instead. Except Kanie Kokoro, she makes her own little group with other girls and keeps her distance from guys. Iba Kouki joins Kazuki's circle because after her whole frame-up scheme against him got shut down, she's basically got nowhere left at school, everyone avoids her, but thanks to Kazuki she's still able to stay friends with Ouji at least. Same with Ushimaki Fuuka, at first her classmates avoid her too, but since Kazuki plays along as the "villain" for it, her classmates end up feeling bad for her and start being friendly again. Except then it backfires because of that photo she sent while changing, which was meant to trap Kazuki but ends up on Ouji's phone instead thanks to the counter-swap, and now everyone thinks Fuuka's an easy girl who'll sleep with anyone. In the end she still gets avoided by everyone else and only really has Kazuki's circle to hang out with.
★ A new transfer student changes everything. Miwa transfers to Kazuki's school, and her looks instantly grab the attention of every guy in class. Kazuki, who knows exactly what her stalker situation led to last time, remembers it's because of Miwa that he lost his whole family. She used her fame as a Vtuber to spread nasty rumors about him, getting his dad fired, his mom killed, his sister dead in an accident. Kazuki knows Miwa's going to look for someone to protect her from the stalker situation, and since Amada's not coming to school anymore, she's going to have to find someone else.
★ Miwa suddenly shows up at the convenience store where Kazuki and Mikoto work. They'd tried to steer her interest toward Ouji instead, but she ends up more drawn to Kazuki precisely because he shows zero interest in her. At first Kazuki thinks she's there looking for a protector for the stalker thing, but really she just wants to hear why Amada stopped coming to school. So Kazuki ends up telling her the whole story from the start, how Amada used girls' feelings to get closer to Mikoto, to the point where those girls ended up framing Kazuki. Even after hearing all that, Miwa still wants to stay by Amada's side and says she'll try to get him to come back to school. She also mentions she's actually Amada's childhood friend, they were in the same swim class once and he saved her back then. (Well, in reality Amada just showed up at the right moment to look like a hero, someone else did the actual saving.)
★ Miwa visits Amada's house to convince him to come back to school. Amada immediately assumes he's the romcom protagonist again since a new heroine's showing interest in him. He remembers Miwa as his childhood friend and figures she'll end up being one of his heroines too. He uses the fact that she's willing to do anything for him to set a trap for Kazuki and Mikoto. Amada tells her he's planning to transfer schools soon and wants her help getting Mikoto to transfer to the same school with him.
★ While Kazuki's out with his sister Yuzu and Mikoto shopping for cosmetics at a mall, he accidentally spots Miwa with an older guy. Kazuki recognizes the guy, it's the same stalker who got arrested by police in the previous timeline. When the stalker asks what's going on between Miwa and Kazuki, Kazuki just says they're classmates, which puts the guy at ease. He then takes Miwa off to continue shopping together.
★ Thanks to Miwa's invite, Amada comes back to school. First thing he does is apologize to Kazuki in front of the whole class, but Kazuki's not having any of it. With Amada back, Iba and Fuuka, who'd been hanging around Kazuki's circle, go right back to Amada's harem. Amada then begs the whole class to help deal with Miwa's stalker problem. The guys get hyped to help out given how popular and pretty Miwa is, all hoping for a chance to get closer to her, while the girls, scared of the stalker, don't volunteer at all.
★ Kazuki obviously wants nothing to do with any of it since he already knows it's all just an act by Miwa to get closer to Amada, playing the damsel in distress. Knowing that Sae was the one blamed for leaking Miwa's info to the stalker last time, Kazuki asks Mikoto to arrange for him to talk to Sae directly. Turns out there's no way Sae leaked anything, since she only just found out Miwa was actually Vtuber Miyabi, and she's actually a fan of Miyabi's.
This reminds Kazuki of that time he saw Miwa out shopping with her stalker. It's probably all a setup between Miwa and Amada, same as last time. Amada, wanting more alone time with Mikoto, has Miwa get rid of Sae by using her hardcore fan to frame her, making it look like Sae was the one selling her personal info to the stalker.
★ Since Kazuki knows Amada's planning to transfer schools and the whole stalker-hunt event is playing out the same way as before, he figures the real target this time isn't him, it's Mikoto. Amada wants Miwa to pin the info-leak on Mikoto so she gets forced out of school. Iba and Fuuka go up to Mikoto's desk and ask if she knew Miwa was actually Vtuber Miyabi. Mikoto honestly says yes, and that confirms for Kazuki that she's the target, since that answer can easily be twisted into an accusation against her.
★ Miwa keeps showing up at the store where Kazuki and Mikoto work. Kazuki keeps noticing a sketchy guy hanging around nearby, like he's watching Miwa. Kazuki figures Miwa's just waiting for a chance to catch Mikoto alone and make it look like she's taking money from the stalker, and it seems like Miwa's already got someone lined up to snap photos of Mikoto looking like she's making some kind of deal with him.
★ Kazuki uses this to turn the tables on Miwa and Amada. Once Mikoto's alone, a random guy approaches her offering money for her number. She turns him down of course, and a bit later Kazuki shows up next to her. By then Miwa, who'd been hiding nearby watching, is nowhere to be seen. (This is basically round one, Miwa and Amada's first loss.)
▼ Straight to the accusation scene
★ On the day Mikoto runs into the stalker, Kazuki decides that same day is going to be when this whole stalker mess finally gets resolved. He lies to Miwa about his work schedule and instead goes with Ouji to track down and catch the stalker. When Ouji spots the stalker approaching Miwa, Kazuki stops him from stepping in. The stalker gets close to Miwa, and Amada swoops in looking like the hero protecting his heroine. Seeing Miwa being "protected" by Amada sends the stalker into a rage, feeling betrayed since he thought Miwa was his and only his. He completely loses it and starts beating on Amada, punching his face over and over. Even with a bunch of guys from class nearby watching over Miwa, none of them dare step in out of fear. A bit later Ouji finally shows up and catches the guy.
1. First loss for Amada and Miwa. When Mikoto runs into the stalker and Kazuki shows up, Kazuki tells the guy straight up that Miwa's just been using him. Says he'll find out tomorrow who Miwa's actually into. Turns out this stalker had actually been helping run Miwa's livestreams this whole time, a super devoted fan who kept supporting her nonstop, even promised a date and a private ASMR session. When photos of Mikoto and the stalker get passed around to the guys who'd been helping Miwa, Mikoto denies everything and explains the guy just randomly showed up offering money and asking for her number. Kazuki backs her up too, pointing out this same guy showed up at their store the night before.
★ A few days after the stalker incident, Amada calls Kazuki and Mikoto over. He looks like he's got a plan this time and seems confident he's finally going to win.
★ Amada, Miwa, Iba, Fuuka, Mikoto, and Kazuki all gather in an empty classroom. Amada's side claims there's someone who leaked info to the stalker. Kazuki assumes this is already settled since Mikoto can prove she wasn't involved, but instead they pull out a photo of Yuzu with the stalker. Kazuki immediately loses it, insisting there's no way Yuzu has anything to do with him. Miwa, putting on a sad face, says it's all her fault for trying to get close to Kazuki, that Yuzu, who adores her brother, didn't want to lose him to anyone else and saw Miwa as a threat, so she supposedly leaked info to the stalker just to get rid of her. Amada, feeling like he's won this round, says he won't tell anyone about this so Yuzu doesn't get bullied at school, but in exchange he wants Kazuki to stay away from Mikoto. Kazuki's answer, no way, doesn't matter what Amada threatens him with.
2. Second loss for Amada.
Kazuki pulls out a photo of Miwa looking real cozy with her stalker and demands an explanation. Miwa, not wanting Amada to find out she's been getting close to another guy, panics and claims it's a photoshopped fake. But someone unexpected shuts that down, Fuuka. Turns out it was Fuuka who took that photo of Miwa and the stalker and sent it to Kazuki. Along with Iba, she'd only been pretending to rejoin Amada's harem this whole time. Both of them, still burned from what happened in volume 1, never actually forgave Amada and honestly can't stand him. Since his behavior's been sketchy ever since he came back to school, they fake their way back into his harem just so they can protect Kazuki and Mikoto, kind of as payback for what they put Kazuki through before. When Amada gets asked how he actually feels about Miwa, true to form, cornered as usual, he just dumps all the blame on her and admits he never had any real feelings for her at all. That line completely breaks Miwa's heart.
★ Something interesting happens near the end of volume 2. Iba Kouki has a nightmare, a flashback to the previous timeline. After she framed Kazuki and got him kicked out of school, she hears the news that both his parents died. Guilt starts eating at her and she tries to get Amada to go apologize to Kazuki with her, but it's already too late by the time she hears his sister died too, and then watches Kazuki kill himself right in front of her. She realizes she'd fallen for a genuinely awful, cruel guy.
When she wakes up, it's like she hears another version of herself telling her to protect Kazuki this time. Except now Iba's not just planning to protect him, she wants to make sure Kazuki and Mikoto actually get to live happy this time around.
