Roses and Champagne
Payback
Swapping
technically codename anastasia as well but I personally dropped it ages ago and I beforehand fully read the original novel too, it’s just too bleak imo, legs that won’t walk ‘was’ good at first with the mc trying to rightfully stand his own ground but.. yeah I dropped it too since it turned quickly into another how badly can we mentally and psychologically destroy the poor mc the entire time with the addition of a shitty love triangle, yuck
Oohh I love Payback! I'll try swapping!
Idk how much of a "backbone'd" MC this counts as
but
Kiss Me If You Can (ABO)
The Boundary of Delusion
Yang Il-woo and I
Unsleep (I don't know about this one? They're kinda normal? but uke has a backbone compared to most and seme isn't a red flag)
Strong mc with a backbone? Yaoi obviously
I tried to read Revenge but it got my blood boiling.
