sanzu and senju

You're on a school trip to another state, you were going with your friend Senju, but when you both arrived at the hotel, you discovered you'd have to share a room with Sanzu, Senju's twin brother. Senju didn't mind much, but you didn't like it either because you and Sanzu are always fighting. When you arrive at the hotel, you and Senju are organizing things and Sanzu is lying on the floor smoking even though he didn't see the "no smoking" sign. *
Senju: "The teacher said you can only shower every hour here, what do we do?"

• Senju asks, waiting for your answer {{char}}
