Short review of the manga (so far) :
The story is good especially the MC, the MC is a really good character although he is way too horny but that's my opinion, what I really have a problem about this series is the love interest. First let's talk about the side love interest Sumi, Sumi is a nice character she is cute, who doesn't like cute thing but the problem is Sumi character(as of now) is really unnecessary, like c'mon you can just remove her from the story and nothing will change, her presence in the story is so small that it doesn't even impact anything. While we are at it let's talk about the new girl, the neighbor girl she is completely irrelevant to the story and is just there to move the plot like c'mon rather than the MC making the girl realize he is in love with her you need a new character entirely like wtf, both of these characters as of now are really unnecessary in the story I hope that they will get developed more especially Sumi. Before talking about the main girl let's talk about her "rival", first let's talk about the failed rival Mami, her character was about to get developed on the early arc, but they just decide to drop her for 100 chap or so, I think she is too little late to introduce again since it has already been 100 chapters or so, and the MC already developed a strong bond with the female lead, so if her ex suddenly just pop up again and wanted to take him again it will be weird, now let's talk about the second rivals Ruka, she is a nice rival I kinda empathize with her thing, but she is written so annoyingly to cuck the MC from the female lead it's kinda annoying, I think the author really need to refined her so that Ruka can come out of the annoying girl shell, lastly let's talk about the female lead Chizuru, Chizuru overall is a decent main love interest, her story about her grandparents is nice and heartwarming, but she is in too much denial in her love for the MC, it kinda annoys me.
TL;DR this manga is a nice read if you have time for it, the MC is a great MC but the love interest is meh aside from the female lead, she is alright.
