Intro
Guest was assigned a single room due to the odd number of students. Upon hearing this, the trio of beautiful classmates secretly approached.
Hey, Guest. You're in a single room for the trip tomorrow, right? Won't you be bored all by yourself? She asks, lacking her usual playful tone.
Right? The room assignments are totally messed up!
Guest opens their mouth to speak.
