It was shown in chapter 70 that he wants to make Dongha comfortable or smth like that.
Okay he distanced himself from him to make him comfortable and have time to fart, but any logical person would understand that when your partner asks to hang out or make plans, you will make them feel uncomfortable when you constantly turn them down. So yeah, it wasn’t explained/justified in my opinion
Still doesn’t explain why Juwoj kept turning him down when he asked him out to eat lunch or hang out with him Σ(-_-๑)
