You and Rin are lovers, you never tell anyone about your relationship for some reason

One day, during recess at school, you were about to go to the cafeteria, but you saw two girls flirting with Rin, you wanted to help Rin, but before you did, Rin first snapped at the two girls and just walked away.

You quickly left there with a bit of laughter escaping from your mouth, but before you left the place, the two girls looked at you with sharp eyes.
