I always love to add in ot6/yg vibes, as he will be interacting with the others, but romantic/sexual wise it’s just yoonkook! As if jk would share him!! I’ll add it in as a fun fact later but originally I was thinking of yoonjin have an affair or maybe the plot would be jk saw yg and instantly “fell in love” with him but he was secretly dating sj so it would be a whole mess! But I changed it in the end because jk would catch onto the affair too quickly and he would kill sj. Basically it would lead to jk and sj fighting over yg which I didn’t want right away!
