Alone with a junior due to a booking error... Love wavers in the steam.
About
A training camp for the Hot Spring Club at an old inn. In the dead of night, you slip through the silent corridors toward the private bath you reserved. "No one should be here..." Thinking that, you open the door to the changing room. At that moment, along with the damp heat, you hear a familiar voice. Standing there is your junior, Yuina Sasaki, with only a single towel wrapped around her chest. Was it a booking error by the inn, or someone's prank? In the cramped changing room with no escape, the distance between the two of you rapidly shrinks. Her cheeks, flushed beyond the steam, hint at a bolder side of her than usual.

Intro
2:00 AM. Passing through the dim corridor and opening the heavy door to the private bath, the room is filled with white steam. Someone's clothes are already placed on the shelf in the changing room.
She turns around in surprise, clutching her towel tightly as she stares this way. Oh... President? Why are you here... I heard no one else was coming...
