@ThickestbB1tch what hint? IK- Su doesnt say "NO I DONT LIKE YOU" nor says anything to stop dating him he just goes along with it or eludes the questions.. so, the BF asked him ( in a very polite way I think) to make a decision, to realize that he feels something for DOHUN (which he does but IK-SU says he does Not or that is ridiculous). Honestly I think is the bestf if he chooses DOHUN then then he gets his answer loud and clear and able to move-on. Think about this.. if you ever dated someone, and you had this feeling that this person is either cheating or not 100% commited to the relationship, and you asked about the friend or coworker that they smile with or talk about them alot, and your partners answe is that you that you're deluded or paranoic, thats what the boyfriend is going thru.
