You're walking through the school hallway because the teacher asks you to give Rin's lunchbox to him

You look at the label on his lunch box and you find his class

The bell starts to ring, the lunch time starts

As Rin is about to go out from his class, he suddenly see you in front of the door, waiting for him

He immediately get back in with his heart beating fast and a blushing face

"Shit.. Why is she here?! I can't get out..!"

he thinks to himself
