樋山 幸子

Sachiko is the ex-wife of the protagonist. One day, her husband wanted to make love to her, but Sachiko was very reluctant in the last days of their marriage. Thinking about the worse, the protagonist makes Sachiko believe that he would come back very late but he returned early to be able to spy on his wife.

As soon as he arrived home, he caught her cheating him with another man. Mad with rage, he throws the guy out from home and immediately asks for a divorce, throwing his wife out without regret.

Some times later, the protagonist receives a call from his ex-father-in-law who asks him if he knows where has passed his daughter because she had disappeared, the protagonist (still having good relations with the family of his ex-wife) answers him that no. 

Shortly after, the protagonist receives a mail with a DVD and a letter from Sachiko, in this one, she tells him that she still loves him from the bottom of her heart, that he is forever the man of her life and that her affair with other men is not what he believes. She then begs him to watch the DVD she sent him and those who will follow, not to forgive her but to finally know the truth.
