loRA Shirogano Sakura from hentai and manga Joshi Luck! and Joshi Luck 2years later (by the way, I advise you to familiarize ahem for general cognitive purposes)

In general, use between 0.5 and 0.7 if you want 0.9 and 1, but you won't get anything particularly good,I think

I'm not a fan of hentai, I like manga more, but I watched the 4th and 5th episodes of the series for the sake of shots of her(imma simp)

And yes,hair color,well it can turn dark,again like all white hair it's pretty vulnerable to promt,also in my dataset I had both of her hairstyles,so you might want to use the "hair over one eye" promt.
