Not my 'Real' Brother

"How did you get this picture?" he asks, having no idea from where she got the picture. 

"From the pen drive of yours," she says in a bitter tone, looking with displeasure. 

"But there wasn't this picture....how?" he mumbles, asking to himself. He remembers only putting the Mo family secrets in the pen drive. So where the hell does this photo came from?

"Shocked, Tingyu Gu?" she scorns, "now answer with honesty, is Chuanli your biological brother or not?"

When Shi Lian saw the pictures, at first, she didn't realize about the surname bit after looking the third time carefully, her eyes diverted to the nameplate, both the men were wearing. The question has been eating here since she realized this. 

"Tell me!" she demands when the man remains silent. "He isn't your real brother, right?" she scoffs, planting her ass on the seat again.
