I think people forget that Mika calls Yuu out on his bullshit more than anyone and always tries to take him out of stupid ideas.

Mika totally supports Yuu but he’s not blind to his faults. If anything, he’s the one who accepts Yuu’s mistakes more than anything and is there to tell him to stop.

He’s not a blind, say, stan of his.

He even called him a bad person for wanting to turn Mika into a vampire for himself.
