[Kuroro Horumu (Kuroro)] Suki na Toki ni Nuite Kureru Oshi ni Yowai Motokano. | My Pushover Ex-Girlfriend That'll Help Me Bust A Nut Whenever I Want [English] [Darg777 Translations]
I want to know why thing broke up. I have guess for the break up though, she thought she was becoming a perv because of him, then broke it off, from the way she acts around him. She doesn't seem to hate him, but "dislike" some of the pervy things he ask. Like a light tsundere.
The most likely reason for the break up for me is that MC pestered her for sex all the time, no dates, no nice moments, no talks, just no stop sex. Possibly it was after a period of normal dating then when he discovered that pleasure it was like a dam broke and all normal couple activities stopped.
