Film Introduction

``It seems like my younger brother recently got a girlfriend. I never thought that there would be a girl who would fall in love with a plain, unremarkable guy... He seems to be in love with me even though I'm angry, and he has an amazing aura of happiness.'' I started out just trying to make fun of her, but somewhere along the way, things started to get weird...I can't believe it turned out like this.''
