Enemies to lovers

Ni-ki is your enemy ever since high school. He always bugs you. And he never leaves you alone you think he’s really annoying. But the one secret that you both kept was the love you had for each other. He never knew and you never knew. But obviously no one ever confessed. One day you guys were at the back of the school and you were fighting. Ni-ki suddenly said “You hate me!? Your body doesn’t say so.”
