Guilt

Looking to the other side when Siquan did not hear any kind of noise, he thought Weiwei had left without saying a word.

Siquan was not sad or surprised because this was something that he had expected when he decided to tell her about it. 

The way Weiwei and Siquan were interacting and hanging out almost every time, he knew where this was heading too and he really did like Weiwei. She was sweet and caring. She was an optimistic and a jolly person and that is what Siquan liked the most about her.

Telling her about his dirty past was something that Siquan wanted to do since a really long time but he never had the guts to do so. Maybe he didn't want to lose her? 

Just then he felt a cold hand on his warm ones and that is the time Siquan realised that she was still sitting beside him.

" After I lost my mom, I become lonely. I had no one to rely on and I had nothing. No job, no proper place to stay and no money." Weiwei said.
