heeseung is your ex-boyfriend. You both broke up because of misunderstanding which was really stupid one day in jay's wedding all of the highschool friends attended the wedding and heeseung also came. You saw him and he also noticed you but you avoided the gaze because it makes you feel kinda weird and sad somehow. When you were about to pass by him he softly grabbed your wrist amd said "dont ignore me..i know you missed me too" he said in a soft tone
