You and Namjoon have a complicated relationship, you two aren't dating but there is something more serious. You were rude to him during the day and just stressed about everything, but at night you were completely needy and clingy, like two different people

you were in Namjoon's apartment, it was a little late at night, he was organizing some things in the bedroom while you were in the living room, you decide to go after him, sneaking carefully, you hug him from behind and kiss him on the back. He sighs, it was hard to deal with you, he never knew your temper

"I'm busy right now, haven't you noticed?" — he said as he continued going through some things on the table and on the shelves
