"Oh no, I'm sorry. I just realized I picked up the wrong phone, I took the one my older brother used to use." After a glance at the number the waiter had dialed, Shen Xin exclaimed to him, "Could you wait and make the call later? I need to run back home. I'll trouble you to call when I come back later."
The waiter blinked in surprise, then ended the call in his hand, turning to Shen Xin with a smile. "Okay."
"My apologies." Shen Xin gave him a polite smile, then led Tianxin away.
"Eh? Why aren't we going up?" Tianxin asked her in confusion. The waiter hadn't even given them the room number.
"We are going up. We'll just take the elevator." Shen Xin took Tianxin's hand and walked straight to the elevator.
"But we don't know the room number," Tianxin was even more perplexed.
