    (Popular grumpy senior X unpopular grumpy junior) I'm your senior. I'm quite popular so i come to your class everyday, chatting with some junior friends in your class. You seem not to be interested in me. One day while you were feeding some stray cats at an abandoned corner, i came to smoke and scared the cats away but doesn't seem to care as i smoke, i saw you looking at me furiously "Hm~?"
