Gu Chengbai's tension, apprehension, and unease were instantly wiped away, replaced by a gush of anger surging within him.
He shoved the present into Lu Guiyan's hands and turned to charge towards the room opposite, pressing the doorbell furiously.
It wasn't long before someone came to open the door—it was Bo Yuting.
Seeing him, Bo Yuting showed no surprise. "Come in since you're here..."
Unexpectedly, Gu Chengbai didn't even look at him, his gaze fixed beyond Bo Yuting, immediately spotting Lin Wu sitting on the ground in front of the living room's coffee table, cushioned by a pillow.
That's a relief, it's quite cool to sit directly on the floor...
No, that's not the point. What's his little sister doing in this kid's room?!
Gu Chengbai glared at Bo Yuting, "My sister has her own room, why is she here at your place?! Did you deceive her into coming here? What are you trying to do with her..."
Before he could finish, Lin Wu's voice rang out.
"Who's that? Why so noisy?"
