Uhm... He chose to break up with yeowoon and chose to hurt him and himself than choose the option of yeowoon's favorability back to 0..???
He chose the option where they'd both suffer, albeit Yeowoon suffering more, poor baby probably feels like so devastated. I personally think he should've pick the other option, yes, it may hurt the MC because maybe Yeowoon's love would be gone but he can always just make him fall in love again, it's easy seeing he knows now that Yeowoon loves him so much.
