Don't know, but I feel like the blond guy from this story and the one from this one " https://www.mangago.zone/read-manga/eishi_tsuji_doesn_t_do_love/ " are two different people.
Yeah, the author probably wanted to justify his shitty behaviour there, but with a pitiful effect, he is still an abuser! The fact that they just treat those attacks like nothing happened is pathetic, the author probably doesn't know how traumatic such situations can be! Even raised the abuser to possible lover rank out of nowhere, he was never treated this way by Mimori, and later after the first abuse there was a moment where Tsuji handed Mimori over to Yuma asking Mimori if he is sure that he wants Yuma....I'm asking? What? Since when Tsuji has any right to Mimori?! Wtf? There is a lot of inconveniences in this manga ┑(￣Д ￣)┍
I don't understand the whole concept, how Tsuji is treated like love rival here?! He sexualy abused Mimori, forced him twice, telling Mimori it's his fault! Mimori never considered him as potential partner, it was Yuma from the beggining, and here we have Tsuji, who is treated as someone who has a chance to win Mimori's heart....what?! And Yuma and Mimori behave like they need to prove their love to him...this is insane, where did it come from?! ヽ(`Д´)ﾉ
