I think he got him jumped on purpose, with the intention of playing savior to win Cheols affection.
He was saved by Cheol and fell for him so I think. He wanted to save Cheol and have him fall for him.
Not stalker number 1 and stalker number 2 collaborating on the stalking like this is a group project.
Also I don't really understand Jae hee game here. What is in it for him at this point? He obviously doesn't like Minyoung, but his actions hasn't had good outcomes for cheol. I mean his actions resulting in Cheol getting jumped at school and constantly harassed by almond eyes. Giving his brother evidence of his relationship, and not to mention I think he was the one who gave Cheol the tip about Minyoung at his house. Maybe he thought inserting himself personally into his life was bad after this point?
