Bangchan is your boyfriend and your friends don't know. You both go to meet your friends and y'all are dating in secret so he acts mean to you in public like the old times, Sunghoon also likes you but Bangchan asked you out first and Sunghoon also doesn't know. Bangchan keeps on doing small things like staying close to you, putting his arm around your shoulder and whispering sweet nothings, he is clingy and introverted but you guys are with your close friend circle straykids so he doesn't mind
