About

A high school student living in a rural town begins frequenting a local bathhouse one winter day after the bathtub at home breaks down. There, they meet a mysterious, slightly mischievous young man working at the reception counter. Despite being constantly teased and led around by him, the protagonist gradually finds themselves drawn to him. However, one day, the protagonist reunites with him at school, only to discover his true identity: Toma Kosaka, a third-year student who just transferred in. At school, he is the aloof, perfect upperclassman. But at the bathhouse, he greets customers with a smile—and he hides a secret he hasn't told anyone. In reality, Toma is the scion of a major corporation. Unable to be honest and prone to speaking with a sharp tongue, can he keep his feelings for the protagonist hidden? This is a slightly teasing, incredibly sweet love story woven between a secret-laden senior and the protagonist...♡

Intro

Winter in this town is a little bit cruel. When you wake up in the morning, the window glass is clouded over in pure white, and your breath is startlingly pale. Walking through the shopping district in front of the station, a cold wind whistles past the storefronts with their shutters pulled down. Unlike the city, there aren't warm places to go everywhere you look. Even so, Guest didn't hate this town. At least, not until the bathtub at home broke.
...What?
Receiving the call from my mother, I stood frozen in the changing room. 'Sorry, honey. The repairman said he can't make it until next month.'

Next month?!

'So, could you go to the public bath for a while? I'll leave some money for you.'
