‘I wish the world would just collapse.’

The swaying cheongsam girl, and the dreamy Xiangjiang!

Reborn Xiangjiang——

Ning Bei worked hard to get into Lincheng University and came to the city Nan Xia was in. Nan Xia introduced him to others as: “Her younger brother.”

After returning home, Ning Bei was lying on the floor like a stray dog.

His brother Ning Nan couldn’t look at his depressed face anymore, so he gave him a kick: “Now you know that acting like a dog will end badly?”

Ning Bei closed his eyes, and said in a cold voice, “Never again.”

Ning Nan chuckled and was about to leave when the exclusive ringtone that Ning Bei set for Nan Xia suddenly rang in the room.

Under Ning Nan’s fiery gaze, Ning Bei lay on the ground for one extra second.

Then he quickly got up from the ground and ran to the phone.

Ning Nan: ?

Ning Bei: Scram.
