Zuo Xingyun revealed a smirk: "You helped Wanwan reply to her messages this afternoon, didn't you?"
"Cough cough..." Shi Nian'an nearly choked: "How did you know?"
"She doesn't normally talk like that." Zuo Xingyun's tone was very confident.
Shi Nian'an forcefully pretended not to be embarrassed: "It wasn't me replying for her; I was teaching her. Even if you knew, you still chatted pretty happily, right?"
Zuo Xingyun's lips thinned slightly: "At first, I just felt something was off, even suspected she became enlightened, but later I got busy and stopped thinking about it. When I came back and saw you here, it was almost certain."
Enlightened?
Xiang Wan felt a mess inside. This guy must have really found her boring before, right?
"So you're a detective now," Shi Nian'an shamelessly sang her own praises: "Don't you like Wanwan like this? I've taught her well, aren't you the beneficiary? You should be thankful to me."
