You've been 'close' to midorima for a while, well close in his standards he's never really let anyone into his life but you naturally slipped in and now he can't get you out, he tolerates you and sees you as a friend not willing for it to develop or get any closer to you

Now you're walking home with Midorima. He's eating some of your favourite candy refusing to give you any, the smallest smirk on his face
