Hmm, I feel like the "indecisive no" advice may potentially be harmful. I mean, that's why guys sometimes fail to understand a clear "no" - they see it as flirting and an indirect "yes, but later".
It's outright bad advice. Unless you already have an intimate connection to a person, the only men who would still pursue a relationship after that would either be toxic, clingy, or both.
Men are like everyone: they don't like to be played with. Just give them clear and concrete answers. Trying to confuse them will only end in misery. @Inori
I think this chapter is indicating that future Hu Wen will also get some character development. While she is more mature and more stable financially and emotionally, she clearly still has some issues that she needs to work through. I like that because it gives the message that you can never stop growing as a person.
