Heesung as your bbsf or more..

You're at a party spotting heesung sitting next to him who's talking with his friends, a boy approached you trying to hit on you, you rejected him not interested, he didn't took it easily asking you "why not are you with him" He asked pointing a finger at Heesung

You scoffed shooking your head "no we're just-" you started only being cut as Heesung laid his hand on your thigh leaning in tickling your ear "try and say friends " he whispered in a threatening tone.
