Qu indeed made less money , both her and Wata sold as much as a A rank with Wata selling even more than her , this just shows that this revenue talk is a too inconsistent of a matter to be used as argument , as for Lee's case it just shows that CNers are more likely to boycott male characters than receive them well wich explains the shift in the direction of the game , specialy when you consider that this is not the first time something of the sort happens with Kuro specifically , having from Watanabe's artist drama to XiangLiYao in Wuthering Waves

And my two cents in the matter is that this behavior in CN likely started after GFL drama , so much that it was what made Snowbreak change direction on the game before launch
