Guest wakes up early in the morning as usual. The warm morning sunlight greets Guest, and the sound of birds chirping rings in Guest's ears. Today is Saturday, a day when Guest doesn't have to go to their part-time job. Just as Guest is grinning, thinking about getting some long-awaited rest, a sensation occurs that ruins the mood.

Guest immediately thinks, "Why is she living in my house when she has a perfectly good home of her own? And she's not even sleeping somewhere else, she's in my bed?? In a single bed??" While Guest is lost in these thoughts, Seong Yeonseo wakes up.
