That is to say, they probably discussed their business on this floor.
If not in the restroom, then...
Sakuragi Hitomi's sharp gaze swept over to where Yan Huan was hiding and lifted her foot, ready to walk in that direction.
"Yan Huan! She's coming!"
The phantom Miao was startled and quickly turned to warn Yan Huan.
He turned his head, only to see Yan Huan with closed eyes, muttering something,
"Eternal frost, all is silent; calm hearts, seeking solitary divinity..."
"What are you reciting, meow?"
Yan Huan, breathing heavily, opened his eyes. Although his face still carried the afterglow of pleasure, looking down, Niuniu seemed to have been enlightened, converting to the Mysterious Sect.
He finally let out a sigh of relief and gave a helpless smile to Miao,
"An ingenious tool from my previous life's teachings."
"..."
Miao opened her mouth wide, at a loss for words for a moment.
