One day, Bossun discovers a box of video tapes in his mother's room. The videos show his young mother, a pretty woman named Haru, and a man who looks just like him...
I continued to watch them in 
secret when my mom was out.
Mientras mi madre no 
estaba, me puse a verlos.
Seguí viéndolos en secreto, 
cuando mi madre salía.
Eu continuei assistindo enquanto 
minha mãe não estava.
