Faithful live-action of Takasagikou original "rapming"! ! A son and Yuta who felt happy on the way they walked and walked, even though their family and mother had two painful family budgets. One day, when I come home from school, I witness that my mother is in love with someone. Moreover, the other party was Yuta, Yuta's best friend. The impulse that I have never felt before begins to swirl in him .... At that time, Yuya's mother who saw Ryota invited him home. Yuta who was swayed by the emotions that can not be words suddenly tried to overthrow her.
