Having resolved Ying Xiaoya's emotional issues, Cheng Su instructed her to prepare the materials she needed, saying, "Once you're busy, you won't have time to dwell on things."
Ying Xiaoya rolled her eyes at her and just buried herself in work.
Cheng Su stayed for a while before leaving. During that time, Xiao Pinshan talked to her about work, but he seemed a bit uneasy, probably guessing that Xiaoya had told her about their situation, hence he felt awkward.
Cheng Su had no intention of blaming him, nor did she plan to teach him what to do. Privately, in her eyes, she naturally sided with Xiaoya, hoping Xiaoya could make a better choice.
So, she wouldn't instruct him on what to do.
