ijun walked in on ha-eon telling his friends that he approached ijun for his money (which is true at first but he ended up having romantic feelings for him) so ijun felt betrayed and used so he broke up with him. ha-eon was basically acting up because he felt bad about his initial impure intentions and his own insecurities (not being good enough for ijun)
wait whyd they break up the first time i js remember seeing someone but idk if i missed it ngl
