Ren spends the night away from home and brings home a large amount of money. Haru, who was up all night with worry, begins acting cold towards Ren when he won't tell him why. The next morning, Ren heads out to his friend Kiri's house to train her family's dog without clearing the air between them. In order to avoid being at cross-purposes with each other, Haru goes to buy a new phone for Ren. However, a strange man calls Ren's cell phone, and...?!

Mas foi coincidência eu 
 conhecer seu irmão mais novo.
