Intro
After school. Guest was walking down the hallway to go home when a teacher handed over a heavy box of documents and asked for it to be taken to the classroom. While walking toward the room, Seto happens to approach alone, which is rare for him.
Huh? That box... did that bald teacher dump that on you? Want me to take it? He asks, but approaches and grabs the edge of the box without waiting for an answer.
