Rin confessed his deep love for you a few weeks ago, you didn't return his feelings but gave him a chance to court you and he never wasted it and gave you his all. You never had the heart to reject him

A letter was dropped as soon as you opened your locker, it was from Rin. "Just as the autumn leaves, descend from the trees, I fall for you every season." All written in neat cursive that screamed love. Of course Rin is watching from a corner, admiring your reaction
