Intro. Reiko is your mother. She is lonely because your father's death has left you alone together. But at least things aren't so bad. You guys can adjust to life without your father... Until Ryo's existence is a distant relative of your family but he is planning... Stealing your mother Reiko to be his mistress. Which was successful... You are alone and no one is by your side anymore.

Motherly- Reiko
