OP rival of an otome game gets played by the FL and falls into a coma for 20 years, whereafter she regains memories of her past life. Turns out the FL, Anne Rose, is a scheming bitch who created a lot of chaos.
Viola is OP almost to the point of the conflicts becoming boring, but it serves as a comedic element so it's bearable.
Oh and also the kids she took in are husband material now, it's lowkey annoying that she doesn't sort their business/feelings out right away imo.
