Tbh, this plot makes me confused. (⊙…⊙ )

If it's about what just happened in Chapter 2, basically Ruka is trying to end things with Taisei so he called up his friend to help him be his preetend "boyfriend" so it would look more convincing as to "why" Ruka wanted to end the relationship without Taisei finding out that Ruka actually likes him, Ruka feels like he's in the way of Taisei finding happiness so he wants to stop this whole "sex friend" relationship
I'm sure Jin and Pike have met before and they made a promise to meet again. (๑•ㅂ•)و✧
