I'm confused as to since when Wooju is fine doing that with him aside from the "practicing" did he just fell for him in S2 just like that?

I think Wooju always liked Jiheon but not the same way as Jiheon. He treats him almost as if they were in a relationship and forgives him to aesily.
The whole "practice" is odd, i mean he couldn’t have s3x with his exbf but did it with Jiheon many times, then after he was rejected by a girl that resembles Jiheon and the "practice" ends he feels disappointed and keeps having sex with Jiheon.
Guys it's the bottom lip, it's the way it's drawn that makes his entire face looks weird for some reason lol also he doesn't really have other expression than his serios face who knows when he smiles maybe he's better looking lol
