Masaki wants to deliver the chocolate she painstakingly made for Valentine's Day.
Just as she is about to approach Shun after school, a girl from another school stops Shun with her own chocolate and a confession.
After witnessing the event, Masaki tries to leave, but Chizuru notices and chases after her.
And somewhere deep inside, really frustrated.
Y en algún lugar profundo 
de mi pecho, frustrante.
Y en algún lugar profundo 
de mi pecho.
E em algum ponto bem no fundo,
 muito frustrante.
