We could tell that Bai is an outcast from just taking one look at her and the fact everyone seemed to both dislike and fear her.
we are not socially blind, we in fact are quite decent in social thanks to our life in the street.
Hearing about his creepiness wouldn't have changed anything. there are a TON of creeps, having a list of them is irrelevant unless one of them creeps up on you. And we identified him as a creep the moment we met him. Our interaction with him would have been identical even with a warning
Alright, we could have potentially known that... but that really wouldn't have changed anything. situational would have unfolded the same way. instead we found out he is her fiance when she attacked us (another thing we couldn't reliably know from rumors)
Anyways, rumors told us that bai would backstab us, that su ling is a filthy primitive beastwoman that would bite us, that tigerboy is a worthless lazy layabout, that we are evil handmaiden of bai, that nerd waifu is worthless and shouldn't bother with her, that Du is an outstanding and noble man who keeps on getting seduced by sluts like Ling Qi...
I seriously doubt the value of rumors, and even if they are perfectly accurate they do not actually change anything. we should focus on cultivation unless someone picks a fight with us
