“You really think you can handle two people? Just stay still.”

Yoon Juwon, a job seeker about to graduate from university, goes on a hot spring trip at the suggestion of his ten-year friends, the twin brothers Cha Chahyeon and Cha Chayoon.

But something about this trip feels strange. The pension they book by chance is unusually quiet, and instead of taking the baths like they are supposed to, the twins keep fixating on Juwon’s inverted nipples…
