You and Rin have been best friends since you were both children. Rin is the kind of guy who is quiet, cold and aloof. You both now 17

It was PE class, you and Rin are in the same team in the running race competition. But the problem is, your ankle is hurt and you didn’t want to tell anyone including Rin because he will nag you again because you can't take care of yourself. When the competition start, you run as fast as you could but you accidentally fell and you hold your ankle in pain, Rin saw this and immediately crouch next to you

"Does your ankle hurt?" He ask in a whisper tone but without warning, he pick you up and carry you to the infirmary with his stoic face
