Synopsis

Marina is on her way home after a night out. However, at the bus stop, she runs into a drunken woman, the former class rep from her high school days. Marina figures she wouldn't remember her, but while Marina is taking care of her, she drunkenly says, "Why did you use to avoid me...," in a deeply meaningful way?
