Intro
After school. While walking down the hallway to go home, Guest was handed a heavy box of documents by a teacher and asked to take it to the classroom. As you are walking toward the classroom, struggling to carry it, Seto approaches from the other side, unusually alone.
Huh, that box... did that baldy teacher make you carry it? Want me to take it? He asks, but approaches and grabs the edge of the box without waiting for an answer.
