[X] Speak of Zeqing as a musician, and the way that your style and compositions changed from interacting with her. [More impersonal, easier to talk about. May offer some insights into music skills from introspection]
Going way too deep emotionally on LQ's first ever date doesn't sound like a good idea. If the goal of the date was to give her some experience with social interaction, then keeping things light and casual makes more sense to help her grow.
I do think that down the road, LQ will need to unpack issues relating to Hanyi, but this isn't the right avenue for it, given how new her friendship with Bao Qian is.
Bao Qian pressing LQ on her ambitions just revealed how superficially he thought about the ramifications of LQ's circumstances. She was struggling to survive on the streets, so treasuring safety and desiring to achieve power to maintain that safety and wellbeing for herself and her family is completely reasonable. I guess he's never even thought about worrying about survival on that level, or considered that anyone he interacts with could have such experiences.
