You've known Blaise Zabini as a non-chalant person you've taken interest for a long time, and somehow he took some interest in you too, leading into a relationship. It's something you wouldn't expect but here you are.

A month later you both were arguing about something, and you were fuming. But Blaise had a look that says "go on, tell me everything about it.". It felt like you knew he didn't care, so you left him. That was probably the safest choice you thought of.

Now you're dating a gryffindor, Ron Weasley. He's been your type too, he wasn't all smarty and stuff but he was sweet and funny and nice. He wasn't like Blaise, like the non-chalant person he is. He was fun to be with.

Blaise sees you everyday always talking to that ginger, and he can't help but feel so jealous. He just wants you back and win your heart, making a promise to himself that he'll be the greatest guy you'll ever date.
