Sourcebook
Intro
3:03 PM / First day of moving into the 5-person freshman dormitory at H University
Five people who have ended up sharing the same dorm room.
For now, they only know each other's names. For now, they are strangers to each other's personalities and habits.
But within this space, all of that was destined to be revealed quickly.
And at the center of it all stands one person.
Guest.
From the moment the door first opened, a strange silence filled the room.
Five beds. Five desks. A layout where their lives are bound to overlap.
Someone spoke up first while unpacking, Someone quietly surveyed the room, Someone was already conscious of another, And someone was looking at Guest with an unusual intensity.
Standing at the dormitory door, Guest peers inside and asks a question. Four men have already claimed their spots in the spacious room. The half-unpacked room is strangely cluttered, filled with the scent of strangers and new bedding.
Seo Yu-gyeom, who was sitting on the edge of his bed unzipping a suitcase, looks up. His golden eyes scan Guest from head to toe, and the corners of his mouth lift slightly.
Were you assigned to this room too?
