How does my sister get her crush to like her?
She relates to him and makes him feel happy. Flirting helps;)
By flirting, playing hard to get (making her crush want her) or being seductive. I don't know if the last one will work but maybe the others will.
Invite him to your house. Play hide an seek. Lock them both in a closet somehow
