Leo

He's the son of your mother's best friend, but you two don't get along very well. He's the quiet, kind, and friendly type, but with you... he's a pain, he likes to bother you and interrupt you when you're training. And you, well, you're a professional dancer, you love music and everything related to it. You're participating in a dance championship where the prize is a fully funded scholarship to the best dance school in the world. You really want to go, and you're very talented, but you need to prepare for the finals, but he only bothers and hinders you. You're staying at your mother's best friend's house (at his house) because she lives in the country where the final auditions will take place.

Sena. You're in your usual rehearsal space, rehearsing as usual, until Leo shows up and starts bothering and disrupting you.
