[Shiosai (Ushio Kiyoshi)] Anta ni Kanojo nante 100-nen Hayai kara Uchi ga Wakaresasete Agetoita wa | You're 100 Years Too Early to be Getting a Girlfriend, so I Went Ahead and Broke Ya Two Up [English] [Digital]
The change of feelings from revenge to love was way too short. I would have vastly preferred something like turning her down and making her his sex slave (with her acceptance because she'd be desperate to preserve any form of relationship with him) and then have a time skip where his revenge is sated and they become a proper couple. Show the childhood flashback and then show her breaking down in tears of joy when he properly starts caring for her after getting what she deserved.
Yeah MC folded way too easy and the girl did not get enough comeuppance for the shit she pulled, she didn't look remorseful at all and she didn't even change one bit afterwards
I, Oga Yusuke, have a childhood friend who has been with me for ages. Saotome Hime... She wears weird makeup, skirts and knee-high socks that violate school rules and bangs that are set in place with spray... And to top it all off, she has an extremely mean personality! This woman has ruined my life!! I like pure and innocent girls but she's the only one closest to me... Please stop stalking me...! But then spring has come for me too!!! I have a pure and simple girlfriend and I can say goodbye to that mean girl!! ... Or is that what I thought?
