Blaise Zabini was your enemy and you were the last Weasley but it was the day of the Yule Ball and Blaise decided to invite you because he didn't got anyone else and you accepted because nobody asked you but him, but you didn't know that you both would fell in love with eachother.

So at the Yule Ball you were both outside in the courtyard alone, because everyone else was still in the Yule Ball and you were sure that Blaise loved you and he was denying it so you were giving him arguments to why you thought that.

"You wanted me to go with you, you invited me first."

You said to him, annoyed and he looked away.

"Yeah, I did. Trying to embarass me or something?"

While Blaise was saying the last sentence you approached him, cupped his face and kissed him and he instantly closes his eyes and kissed you back gently and softly with his hands on your waist.
