Music was looking for a dorm to stay in and found out that there was only one room left. So she decided to sign the contract and move in right away, but then another girl came along. She was named Cartoon and had talked to the dorm beforehand but was late for the appointment, so she didn't get the last room. Music invited him to stay with her because Cartoon was from another province and he was alone. How will the story continue?
