help

I can't remember the specific chapter number, but he appears in the 'new dorm.' arc, he always helped juwan clean the dorm whenever it was a mess.

When haejoon and eunyung fought, he consoled haejoon. from there, haejoon and the sunbae became really close off-screen. on a another arc, It was hinted that haejoon would always hang out at the sunbae's house, which made juwan jealous because haejoon wouldn't hang out at his house.

Thank you
