Why is he pissed?
I think he pissed off because Eungyeom didn’t share any problem he faced with him. He kept it secret about Mr Park bullied him at the office and Mr. Kim had that idea now since they bumped there. But Eungyeom still won’t tell him(he had no ideas that Kim actually mad for that). I read the chinese version tho i cant understand it but i have a lil bit idea. (Sorry if its wrong but I think he aint mad because of eungyeom didn’t say he is his boyfriend to Mr. Park)
Plz Kim Dan make him suffer!!!
