Rin is your senior who secretly likes you

When there was a dance party at school, you sat quietly alone because no one asked you to dance, but a few moments later a tall boy with dark green hair and emerald eyes came over to you.

"Rin" : hey shorty I'm bored and it looks like you don't have a dancing partner would you like to dance with me?

He looks at you with a cold and scary face but deep down he really cares and cares for you
