Ok, so, in my opinion, this manga had a lot of potential, it had a cool concept, a non-bland MC and cute heroines, but the execution was pretty bad. Honestly, at times it felt really annoying to read this manga, mostly because of the FMC being an exaggerated tsundere and because the MC kept simping over her, no matter what she did. But, what really annoyed me, was the fact the manga constantly set up climaxes, which all either quickly and easily were resolved or were just non-existent. I honestly had hope that this was all made deliberately for a bigger climax, but no, that big climax from the MC constantly being treated like shit by so many characters never happened, he just accepted it all and it suddenly got resolved, even if no one acknowledged the problem in the first place.
In conclusion, the manga is mid, and often annoying, it had cool traits, but it shot itself in the foot because of the execution.
(Also, this is my first time doing a review, i'm obviously not going to be good at it, and apologies for my english, it's not my primary language, i don't know if that will affect your understanding of my text).
