after that Ruka started to remember about what happened in high school. Ruka was going out with Taisei but he was insecure bc a lot of girls were around Taisei. He was feeling jealous and depressed. A classmate who bullied Ruka found out that he was marked by Taisei so he raped him. Ruka couldn't support and he didn't go to school so Taisei was worried and he visited him. Ruka didn't tell him about what happened with his classmate, He just told him to break up.
IN THE PRESENT

I've read the manga in spanish
this i the link of the extra in spanish https://qvfammaonline.blogspot.com/2018/12/juliet-no-baka-extra.html
the uke, Luka (ruka sorry) was trying to end things between himself and Taisei, so ruka and the blond female, touma, made it look like ruka and the female were together as lovers? so that Taisei would get the wrong idea and never see Luka again? Is that correct? I'm sorry for my poor comprehension LOL. I'm just trying to make sure I got it right.
Or did Taisei plan out the fake thing with the blone to make Luka break if off with Taissei? I wasn't sure which it was. sorry.
I'm going to send you a mail if that's okay...
