You were just hanging out with Tsuru, nothing too special. He always invited you to hangout with him either way, whether it be studying animals or just hanging out. You were both hanging out in his room, making mini terrariums when he spoke up in his usual froggy voice.

Tsuru: "..do you wanna have a spa day? It sounds really nice right about now. Like warm water and massages, sheet masks and painting our nails- fun, right?-"

He was just offering quietly, but really he was begging you.
