After taking a perfectly ordinary shower, Yun Feng returned to her room and opened the door, only to find Yun Jin inside.
After the initial shock, Yun Feng listened to Yun Jin’s question and made a guess. Yun Jin was a little sad to hear that she might not be able to go back, but after Yun Feng talked her through it, she decided to stay and look for a way home.
However, when Yun Feng’s parents returned, they told her that she and Yun Jin were sisters. Yun Feng was confused and had no idea what to make of it. As Yun Jin stayed on, many things happened between her and Yun Feng, bringing them closer and closer.
