It couldn't be anyone else but his girlfriend.
Gu Yuansheng took a second look and felt a little uneasy.
Why was Dr. Shen's other half calling him on his cellphone?
Had he done something wrong?
After running all the possibilities through his mind, Gu Yuansheng answered the call, "Hello."
The voice sounded very young. When Fang Tongtong heard it, her eyes lit up. She said, "Hello. Is this Dr. Gu Yuansheng?"
"Um… Yes, it is, Sister-in-law."
Sister-in-law?
Fang Tongtong was stunned at that sudden form of address, but she quickly realized who the guy thought she was.
"You're mistaken. I'm not Shen Zhilie's girlfriend. I'm his girlfriend's best friend."
Gu Yuansheng breathed a sigh of relief when he heard that and asked, "How did you get my number?"
