Do you remember that young man named Wang Yuhuan? He used to be your student, confiding in you during the low points in his life.
You could tell he admired you, right? You used him, summoned him to Qi Yuan, and arranged for him to stay at Sesame Apartment to gather intelligence and provide cover for you.
You're not entirely unaware. Jiaobide secretly asked you to gather information on Sesame Apartment, forbidding you from asking why.
And you actually didn't ask, not only helped willingly but also dragged a trusting Wang Yuhuan into it. Even if you didn't know the truth, didn't you find Jiaobide's motives suspicious?
You must have suspected it, but for personal feelings or some private purpose, you still went ahead!
