She was neglected by her family since she was a child. When she was shopping with her mother, she was hit by a drunken father who was driving. Then, in order to prevent outsiders from pointing fingers and affecting the image of a lady, her parents hid her sister in the kennel. Sister heard "I" (in the game) because she didn't know her life and death. When it breaks out, she will kill me.

The first scene * * * has four endings. This is a story from a true ending. Only by solving the ending of "killing sisters" can we solve the real ending.
