Ji Xiaolan saw that they hadn't come back for a long time, so he got up to have a look. The three of them stood outside the door, wondering which one was playing the piano.
However, they alarmed the beautiful woman in the room, and the three of them slipped back. Suddenly stopped by a maid, this woman is Du Xiaoyue.
