I'm confused who is the partners here????

I think the big guy and the black haired guy like each other and the blondie is still in he’s closet or sum

Kai is flirting with Mickey but actually has a crush on Alex. I don't know if he used Mickey as a way to get close to Alex or if he just likes to mess with him.

At the beginning I thought Alex was in love with Mickey but I guess he is just overprotective as a friend. And he seems to warm up to Kai.

Mickey seems to have feelings for the teacher but still hasn't realised it himself. He thinks that are feelings of admiration.
