He is

So why is he doing all of that? I mean what will happen when he sees him at the wedding? Can u please explain to me ?

Sorry I dont have all the spoilers but I think you can find something in the comments, all I've heard is that the uke's father assaulted the seme when he was younger and he's doing all this to take revenge on them, but this has a happy ending so I think they will eventually fall in love
