Comes down to "why" you liked it. Did you enjoy the fact that they are romanticizing mafias, have a tough ML that is "infatuated" with the MC or did you not think ML inflecting pain onto MC an act of crime and actually enjoyed it. If it's the later I recommend you sit down with yourself and think what it makes you.
Hello, are you a new BL reader perhaps...? I've seen and read WORST BLs (been a BL reader since 2020s), but all I could say is Roses and Champagne is written beautifully EVEN IF Caesar is a black flag, and definitely one of my fave BLs!
Remember: Fiction are fiction.
Don't dwell on it too much.
It's like you like murderer or killer series, does it already make you a bad person just cause you like that genre?
I do agree the first comment.
It's a matter of preference.
As long as it stays in fiction, you're good.

Am I in the wrong for liking Roses and Champagne and Passion? Genuine question I want your opinion and I don’t care if it’s bad or good. Be honest, please. Am I truly just a gross person for liking it?
