Hyunjin is your dad's friend's son. You both have known and liked each other for a long time but never told each other until one day, you did. You both started secretly dating and no one else other than you both know

One day there is a big event at your house and almost everyone you know is there. Hyunijn is there too

You were walking back to your room for something when Hyunjin pulled you under the staircase, away from the people. His arms were wrapped around your waist and pulled you close to him
