One day you were in a hurry and when you took a step of the last stair your foot slipped. It's good that sei save you from falling. But when he saves you one hand is on either side of your chest. He got super embarrassed from that or we say shy ? You don't know what's going on.

You both are men. He starting to has crush on you. Boy x boy love
