Unless he's literally just an asshole fake friend that's highkey jealous of him（￣へ￣）
I think that's the actual case. I think it's an obsession and now that Sahn knows that Dojin is dating a guy, he might be delusional enough to see a chance.
Smh Sahn is totally NUTS. It's crazy to think that there are actually people like this!
My guess is that Sahn's got a crush on Dojin so he spread bad rumors about their relationship to break them up. Now after finding out he's in a relationship with Taehee he's like, "And I'll DO IT AGAIN(▰˘◡˘▰)"
