To clarify this, it is first necessary to figure out how the other party knew that Yang Xinran was Lin Xi's roommate, and that's why they manipulated Yang Xinran to get close to Lin Xi.
Everyone was sitting together to ponder upon this, but Lin Xi looked at Gu Fan with hope in her eyes, believing Gu Fan would have the answer.
However, as a professional, Su Hui asked: "Lin Xi, you mentioned that Ning Qi has been to your dorm room before, but Yang Xinran wasn't there at that time, so Ning Qi shouldn't know that you and Yang Xinran are roommates."
In response, Lin Xi shook her head: "Yang Xinran wasn't in the dorm then. Someone asked me if I'd seen Yang Xinran, so Ning Qi knew that Yang Xinran was my roommate. Although, Ning Qi probably hadn't met Yang Xinran. Even if she knew I had a roommate like Yang Xinran, she wouldn't have known what she looked like."
