27 HOSTAGE?

"Do you two know each other?" Suyin asked, linking her arm with her fiance's arm before looking at Heya, waiting for her answer.

Heya was still stupefied. She tried her best not to show it but could not tell if the others could see through her facade.

How did this happen? Her head was almost spinning as she tried to process everything. Firstly, she was standing right in front of Zhu Liang. Secondly, she had met a really nice girl who she was fond of and thought maybe this trip wouldn't be so boring because even though Suyin was a chatterbox, she was a nice company and made Heya feel good about herself. And lastly, Suyin's fiance was Zhu Liang!!! How? 

How did they even meet? Suyin have not been in the country for a long time right? Also, how come she didn't hear any rumour about Zhu Liang getting married?
