Lin Qiao didn't open the door entirely, so Lu Junjie didn't see Junjun and Tongtong, who were behind the door. But at that point, Tongtong said something.
"Mom, I'm hungry."
Lin Qiao glanced back at the little boy and realized that it was dinner time, and the kid should eat.
Lu Junji stared at Lin Qiao with both surprise and doubt. He tried to lean his head forward to look inside the room; meanwhile, he said with disbelief, "Is someone else in there?"
In fact, he wanted to ask if there was a child in the room. However, as he heard the child call 'Mom', he figured that more than two living beings were in that room.
Lin Qiao opened the door entirely; nothing needed to be kept secret anyway. She needed to find a way to stay around Lin Feng and the others, so she couldn't let them suspect her of having ill intentions. Without question, she wouldn't keep any member on her side secret from them, as they all needed to meet each other at some point.
