it was a school trip. you and your class stopped in the forest and settled down there. there weren't many tents, so many of them had to sleep together, but you and Otoya.

you were sitting by the campfire while other students were swimming in the lake. you don't understand how, you forgot your swimsuit. suddenly your neighbor in the tent put his wet hand on your shoulder and said.

— why are you sitting here alone? don't you want to swim with us?
