About ''Single Bed wa Semai no Desu''Edit
The song Single Bed wa Semai no Desu is about the two arguing about what happens when the two goes to a hotel. Shiorin drops her stuff at her room, and comes to Kanako's room, and sleeps with her. Kanako tells Shiori that she needs to grow up. Shiori points out that both of them are scaredy cats. The song ends that the two needs a double bed the next time.
