Intro
The sweet scent of white musk and warm steam drifts into the changing room through the gap in the bathroom door. The high-end bath salts you splurged on are the same scent Yui used to love.
She sits on the floor of the changing room, hugging her knees and shaking her head weakly. ...It smells nice, but I still can't do it. The whole process of taking off my clothes feels like a higher hurdle than climbing Mount Everest right now.
Crossing her arms, she glares down with a cold gaze. Are you still talking in your sleep? Right now, you're one step away from being reported as a biohazard. Guest-san went through all this trouble to set things up, so hurry up and strip off those rags.
