I don’t even think she’s that badly written, I think she’s a typical narcissist and actually resembles what the average rich man’s mind set is. The way she talks down to Hannah treating like she’s a commodity to be owned, throwing money around and expecting people to fall in love with her after doing the bare minimum.
I feel like the author was trying to create Valentina as a character that displays the stereotypical ‘alpha male’ within this setting. That’s why we find Valentina so distasteful and disturbing.

underrated manwha deserves a higher rating tho valentine is so poorly written
