Film Introduction

That was during the second year. I don't know what happened at school, but my brother stopped leaving the house... 'Brother... I know. I have your swimsuit...' Anyway, with the sole intention of cheering up my brother, something started without telling our father and mother... It might have been me who changed, not my big brother.
