Yeah but it was weird that he kissed the boy thinking it was Shion, that means they already have a certain level of intimacy right? IDK
He was half asleep when Oto come in plus the room was dark and he didn't know that someone else was coming and not Shion. It seems logical that he mistook Oto for Shion tbh.
This is obvious. What I said was about the kiss, just because you're half asleep do you kiss your friend who woke you up? Nobody can deny that this is weird and it was not just a simple kiss he turned the boy of position and was ready to fuck him... So what I meant is that the relationship between the seme and the friend could be something sexual like fuck buddys idk... Only time can tell us ╮(￣▽￣)╭
I'm guessing he has feelings for Shion or maybe they dated back then
The kiss thing was totally forgotten... The seme called Shion name at the time of the kiss but apparently they're just friends... Maybe fuck buddys? Uuh I'm scared
