In front of the door, Yuta turned back and said to Kappa,
"I will go to the river tomorrow before I go home!! Is it OK?"

"Hmmm... Ah, of course."
Tears seemed to fill Kappa's eyes.

"Great! See you tomorrow."
Yuta entered Grandmother's house as usual.
Kappa could hear Yuta saying "I'm home", in a cheerful voice.

Kappa was staring at the door that Yuta had just entered.
"I had a great time. I'm really, really happy."

"...goodbye"
Kappa wiped his tears, and returned to the river.
