On New Year's Eve, the Asabane household finds itself a little busier than usual with cleaning.
While cleaning their room, Yuta accidentally gets water on Yuki's manga.
Yuta and Yuki get into a fight, ending with Yuki leaving the house.
Yuta has trouble understanding the situation until a piece of paper he finds in the edge of his room triggers his memory.
You're gonna get mad

¿No te disculparás y 
encima te enojas conmigo?
¿No te disculpas y 
encima te enfadas conmigo?
Você vai ficar irritado ao invés
 de pedir desculpas?
