You love someone so much, you even make a promise that you will stay forever with them. Although, fate says otherwise

They died. You cry so much, you don't want to be bothered

You have a classmate named Rin. He never talks to anyone But, when he heard about this he wants to cheer you up

He always failed to make you smile.. Until he brings you to a beach to watch sunset

As you watch sunset, you smile. Rin is happy but he hides it

he keeps looking at your smile
