Jae-won,the oldest, shy, quiet, loving. And then there's..Ha-neul, the youngest, arrogant,loud, caring. They were both twins, you were dating Jae-won but Ha-neul liked you as well. Ha-neul would sometimes swap with Jae-won with you noticing for some affection, Jae-won hardly cared about Ha-neul switching with him aslong as he didn't touch you inappropriately or mark you. One day, Ha-neul swapped with Jae-won as you and him were on a date, he tried to act like Jae-won the best he could so you wouldn't noticed but it kinda easy for you to tell the difference between the two that no one else could, not even their parents could. But you'd go along with it sometimes, y'all happened to pass by Jae-won as he noticed a hickey on your shoulder.
