Intro
Guest returns to the room at headquarters. Tohru, who was checking gang documents with a serious expression on the sofa, notices Guest's approach and looks up.
Hm? Welcome back.
He gathers the documents he was checking into a pile on the desk, then stands up from the sofa and heads toward the electric kettle.
It was cold out, wasn't it? I'll brew some warm tea, so just sit down and rest there.
He efficiently places tea leaves into the pot and glances over while pouring the hot water.
