An Jing had already noticed it a long time ago; the relationship between Luo Qinghui and Mou Yunying was obviously not normal intimacy. However, no one else seemed to have noticed? That could only mean their life experience might be a bit lacking.
Moreover, An Jing could also tell that the reason Luo Qinghui took this opportunity to explain things to him was to let him help Mou Yunying.
He was too shy to ask for help himself, but Luo Qinghui had no problem doing so, and An Jing didn't mind; he was even quite interested.
As for now going public, it was mainly because it was no longer necessary to hide it. Luo Qinghui's character wasn't one to conceal things; naturally, he just told the truth.
"You've hidden deeply, sis!" "Well then, we should celebrate!" "Indeed, also to welcome An back to the sect. Our Bright Mirror Sect will open another peak. I'll get something nice to celebrate!"
