Golf is taken by surprise with this new revelation. Bank is younger than him by four months, but this doesn't ease Golf's discontent at all. He does not want a new family, including a younger brother. After initially treating Bank badly, Golf and him can't help but get close. Will the feelings of love between siblings grow beyond that?
