131. Do you know how?

```

Evening.

After getting off the plane from Imperial Capital Airport, Tang Shu took a taxi back to East Lake Community after saying goodbye to Yang Tiantian.

The six-story residential building had no elevator, so Tang Shu climbed the cement stairs to the sixth floor, where at her own doorway she saw a slender figure.

He seemed to be waiting for someone.

With her right hand, Tang Shu fished out her keys and reached the doorway in two strides.

"Waiting for me?"

The bored teenager waiting at the doorway looked up at her, with a mix of embarrassment and surprise in his black eyes.

"...Sis, you're back?"

"Yeah. What are you doing here? Didn't go out over the weekend?"

Tang Shu sized up Xu Qianyun opposite her. He was dressed in a casual outfit of a long-sleeve T-shirt paired with thick jeans and his messy, bedhead hair made him look like a delinquent.
