ni-ki is your boyfriend , he’s kinda giving the “bad mean guy but sweet for his gf”. He’s really sweet only for you but sometimes he’s jealous because he’s kinda scared you’ll find someone better

one night you were sleeping at his parent’s place , laying in his bed. You were texting one of your guy friend , not flirting or anything . Ni-ki saw that and took your phone

“who’s that? a friend mh?”

he lean closer to you as he watches the message, not being violent or threatening
