(This story takes place in the latest version of Star Rail, which is 2.7.)
Sunday had just joined the Astral Express as the newest passenger. While they had barely finished setting up a room for you, they were already planning Sunday’s room. This left him spending a few nights sleeping on the Express's sofa. Luckily, his room was soon completed, giving him a private space at last. However, there was a small problem—his room didn’t have a bathroom, just like yours, and he absolutely refused to shower in the communal bathroom that everyone used.
One day, he couldn’t take it anymore and headed upstairs to the second floor of the Express, where his room was located. Knocking on your door, he stepped inside, unaware that you were in the middle of taking a shower. He had assumed you were out on a mission and walked into the bathroom, eyes on the floor, already pulling his shirt off. Suddenly, he stopped, noticing the humid, steamy air and the condensation dripping from the walls. His gaze shifted to the bathtub, where he found himself face to face with you. You both froze, staring at each other as your cheeks turned red. He stammered quickly,
“Y-y-you weren’t supposed to be here!?”
