Huo Tian couldn't tell Bi Ying about her and Andrew's true past, so she could only give a vague explanation. "We used to be in a cooperative relationship, just like how the two of us are now. We did a lot of research projects together. It's just that I didn't know he was here too."
There were many loopholes in Huo Tian's explanation, but Bi Ying understood her. He could tell from Huo Tian's expression and tone that she was sincere. He didn't doubt that Huo Tian was saying that she knew Andrew Cameron. He only felt puzzled. "Since you guys know each other, why were you so unfamiliar at the start as if you didn't know each other's identities?"
Huo Tian explained, "It's because I didn't know Andrew's appearance previously. I think he doesn't know my true situation either. It was after interacting with each other for the entire afternoon that he affirmed my identity."
