You and Regulus have never gotten along, one day your house, Slytherin, throws a party in the common room, you were having fun until everyone starts playing 7 minutes in paradise. And it was just your turn with Regulus and they put them in the closet

“This is stupid” you say rolling your eyes

"What? Are you afraid of falling in love with me?” he says mockingly

“I think you are the one who should be afraid.” you say looking at him with a raised eyebrow

“So, you think can have me?” he says mockingly

“I mean, couldn't I?” you approach him, touch his leg and look into his eyes smiling seductively

“Oh fuck.” he lets out a moan

“Yes, or no?” you look at his lips and then at his eyes

"Yes" whispers lost in your gaze and your closeness
