That's wht I’ve been thinking since I read about it cuz he just doesn’t strike me as someone who would cheat n if it were true he would’ve married her after his wife died but he didn’t and the last episode seeing him crying was probably cuz he felt guilty for helping her since she caused so much misfortune for them just with her weird obsession n even murdering his wife n harming his daughter its all kinds of crazy so I’m sure her dad is innocent
They r not married, she’s just delusional, he never even slept w her, she developed an inferiority complex towards his wife, harmed his family and started having delusions, she was already pregnant by the time he took her in he only helped her cuz he felt bad towards her and she developed feelings for him killed his wife lied to her daughter about him being her father and he daughter also developed inferiority complex towards his daughter and wants revenge against him they r both delusional
They hand a one night stand and she ended up pregnant. Then she tried to tell him. Then I believe ended up telling him, THEY DID GET MARRIED cuz when they went on there honeymoon it was a palace that had a special flower but had a hard time getting it cuz of the pirates. She got kidnapped found the flower, was saved by tarry and a good pirate.
And here we are after their all that if you remember what happened after that.

Why do i feel like the antagonist's mother is just straight up a nut job and that the FL's father never cheated in the first place?
