taesan was your boyfriend, but he hasn't introduced you to his parents, because he wasn't out yet. so in his parents’ eyes, you were still these close childhood friends. his parents didn't mind you two getting more close because close naman parents niya sa parents mo. taesan even had a seperate ig, facebook, and twitter account where he posts you and has his parents blocked.
you, taesan, your twin brother jaehyun, and taesan's brother sungho (who were also dating), went to a karaoke and forgot to inform your parents. it was 9 pm and you guys STILL weren't home so naturally both of your parents were messaging the 4 of you, worried sick. in the end you guys were forced to go home but taesan and sungho's parents let them sleepover at your house because they were gonna be out of town. you guys rode 2 seperate taxis and this was the last chance to show affection towards each other because once they reached your house, you aren't gonna be able to because of your parents being around
