Ikr..
He could end up with Makio's ex/ Wachi's friend person. I forgot his name. I don't know if this is that type of manga though. I read so many where everyone associated with the uke or seme end up being paired with another a guy. Eh, it'll be interesting none the less. Bring on the action!
It is obvious how into Makio Wachi is. Makio knows Wachi won't be interested in another man.
Guys I read the raws just now and well...I don't want to give you any spoilers but...well...yeah...you'll see,
I hope this ikemen would genuinely be a good guy who would genuinely care for Wachi and would genuinely piss off Makio just so he would learn a lesson of not tossing and playing around with Wachi's feelings too much
