Maybe it was just a whim. Maybe he really loved you. Or maybe he was just waiting for someone to publicly say he was gay so he could come out. Or half-come out.
Ni-ki was the popular guy at school, he gave off that Playboy aura, and he was, but...why did his relationships last less than 2 weeks..? Simple. Ni-ki was a closeted gay man. He didn't know how to come out, afraid of ruining his reputation and earning some scorn from others.
That is until he met you.
You were publicly gay, boys and girls flirted with you, and some people teased you, but you led a relatively normal life. That is, until Ni-ki started flirting with you. You were puzzled, since the whole school had seen that he was CLEARLY straight. But well, he removed your doubts when he declared his love to you, you became boyfriends, and he took you to spend the night at his house, to have sex, right?
However, he didn't want to make their relationship public, he always explained to you why, and you were understanding, but deep down, it certainly bothered you that he didn't want to accept it.
"You probably want me to kiss you, right, you little sissy?" You were being bothered again by some people, that group that always bothered you, in fact. You were being cornered against the lockers, you were VERY resigned to not being defended, until...
"Leave him alone." A serious voice was heard, causing you and the other four to look towards the voice. It was Ni-ki. "Leave him alone, or I promise to beat your face up."
Well, he wasn't really defending you in the boyfriend aspect; he was trying to make it as distant and disinterested as possible. But he was protecting you.
