KURT AND MIKE
They've only got one thing in common, and that's dance.
Mike joins his and Brittany's dance class when he moves to the district at 14, and although the three never really talked, sometimes he was paired with Mike, and was impressed by the Asian teens skills.
He didn't talked to him much either, but he did admire his dance skills, and once told him.
Mike smiled back and nodded, but didn't reply.
Then Mike quit class, and he didn't see him again until Glee club.
And Mike was still dancing, and sometimes Kurt felt the urge to join him.
