Tong Mo suddenly became agitated, "What nonsense are you spouting! Tong Mo and I have been best friends for over a decade, I wouldn't harm her even if it meant harming myself. Stop trying to drive a wedge between us!"
Actually, even without an explanation, Mengmeng would have believed that Tong Mo wouldn't do it.
So... it could only be...
Xu Wenting!
Xu Wenting saw everyone suddenly looking at her and quickly shook her head, her gentle and sweet voice tinged with a hint of grievance, "Why are you all looking at me? I don't even know Luo Mengmeng. If I were the one who did it, what would my motive be?"
Upon hearing her explanation, everyone immediately stopped suspecting her.
After all, Xu Wenting said she did not know Luo Mengmeng. Since they didn't know each other, let alone have any grievances, it was unlikely that she had done it.
As for Tong Mo, being close friends with Luo Mengmeng for over a decade made it even less likely that she would harm her.
