With that, Ding Yixin naturally started walking toward the stairs.
Seeing him act so calmly, Rong Xingyu felt a sudden pang of unease in his heart.
But for the moment, he couldn't think of a better solution.
He was also worried that Rong Zishan might unlock the door and come in at any second.
He tiptoed forward and quickly pressed his lips to Ding Yixin's.
"I'm sorry for the trouble, Dr. Ding!"
Then Rong Xingyu turned around and ran toward the door.
He ran so fast that he almost slipped on the floor.
Rong Xingyu noticed the door lock had been secured from the inside.
He blinked his eyes in surprise, did Ding Yixin accidentally lock it just now?
There was no time to think about it.
When he saw Ding Yixin's figure disappear up the stairs, he quickly opened the door.
As soon as the door swung open, Rong Xingyu saw Rong Zishan leaning one hand against the doorframe while the other held a phone to his ear.
