U can go here to read more (and it's based on the light novel I think): https://www.novelupdatesforum.com/threads/the-bondservant-%EC%A7%91%EC%B0%A9%EC%9D%80-%EB%8B%A4%EC%A0%95%ED%95%98%EA%B3%A0-%EC%A7%91%EC%9A%94%ED%95%98%EA%B2%8C.172524/page-5
Basically:
●Brother makes FL write a letter saying she hates ML or something
●brother fakes MLs death and shows FL
●ML becomes Duke again (he was unconscious then shipped back to his country and ended up Duke again)
●FL adopts her nephew (girlie died during birth)
●FL is forced to be with rich dude but escapes to diff country (where ML is)
●ML and FL bump into each other
●FL doesn't believe ML is ML (coz he "dead") and lies and says that the nephew is her son
●ML (who is on drugs and an alcoholic now) goes crazy coz he's like "u left me for his money" (it's what the letter said too)
●FL realizes he's actually the ML and tries to explain everything
●ML is like "NAH, I don't wanna hear it, just know ure mine"
●other details that show the misunderstanding was coz of the brother and the ML's step mom and stuff (I whole other thing)
●and yea, they patch things up and life happily ever after
Honestly, they both kinda dumb with their misunderstandings, but ig I KINDA get it with the situations they were in, but likeeee why trust the brother/step mom over each over (● ̄(エ) ̄●)
That had better been a dream, COZ WHAT?!?!
