I have a relative with a bit similar situation. The husband was dying and he told his brother and wife to get married so that his properties will be left to his brother and children since its part of our culture that a woman must be married, if she became widowed then she must get remarried so the husband's worried that his wealth will be taken from his chidren.
The woman married her bro inlaw and took her husband's retirement money. The thing is, she had an argument with her aunt. Its her aunt who processed everything/documents, so naturally she wants some money or payment and they did not gave it so as a revenge, she ruined the dead husband's plan.
The brother is impersonating his dead brother so that he will take everything he left for them. Soon, all the money was spent as its not their hard-earned money.
I always thot that i will not be able to take it if my husband cheated on me but only right now today did i realized that i knew that my ex husband has been cheating on me but i dont care about it because i never loved him. I really look pitiful, never experience romance love and only felt betrayal and hatred thru reading manhwas like this....
Well I experience betrayal and hatred since after divorce that bastard took our business and motorcycle and owed money from my brother. D*mn him.
