Innocent and vulnerable

"Darwin is Weilong and Mo Yihong's old acquaintance. Apparently, they were very close until your father left the country twenty years ago. I think they were still in contact but they never met in person, though Weilong and Yihong were in constant touch." Jason explained.

"Close? As in friends?" Yufan inquired.

"Hmm not sure yet, information about this Darwin is very precise so I'll have to do some digging which will take some time." Closing his laptop, Jason frowned, "I also have a feeling that his real name isn't Darwin, maybe it's something else."

Thinking for quite some time, or a while, Yichan specified, "I think whoever sent that mail kidnapped that Darwin guy to lure him back to the country."

"Yichan I think that your father is in danger, we need to be careful," Yufan suggested.
