Have you read the novel ?
A bit, yeah, but although there are some difference in term of who abused the ML, and how the ML was affected,
Still, the base of the plot is the same,
the FL wish for an amiable divorce,
the ML being capable to grow his influence, power and wealth in the shadow,
their marriage was arranged when they were kids,
got married, the ML first find the FL untrustworthy,
the FL try to protect the ML,
the FL convince the ML she's on his side and wish to be friends, they became closer,
the FL try to show her sincerity through actions more, the ML came to trust the FL more,
then when they grew up the FL ask for divorce and the ML refuse and the drama continues,
the only difference is the FL is aware from the start that she had developed feelings for ML, so yeah...
Well, I could give credit to the healing arc from abuse dedicated to the ML but really, although that part of being so negatively affected by the abuse he detests touch and women is a HUGE difference compared to the ML in 'The villainess wants a divorce', but it doesn't change the fact that the author for this story most probably built I failed to divorce my husband based on that story since 'The villainess wants a divorce' was published a long time ago
Huh isn't that manhwa with characters named caesar and canaria? I read that one and i love the story, but i never think it's a carbon copy, there's a similarity but not necessarily a carbon copy... It's not like there's no other manhwa with this kind of storyline, i read a lot of manhwa with villainess FLs who want a divorce so i lost track and stop thinking what's similar anymore since there are soooo many villainess FLs who want a divorce but failed child MLs that got abused and healed by FLs is also not a special story, there's a bunch of them... Kids marriage between noble families also really common in other fantasy manhwas... It's unnecessary to say it's specifically based on one manhwa because this is a popular troop, not to mention it's only a promo, so you don't know what's more of the story, most promo tends to look generic, you don't know the details
Like the only difference is the ML isn't a prince...
