My Billionaire Fool Husband

In the family that owns a large business group, the son in line to inherit is understood to have been left mentally impaired by a car accident. A woman who makes jewellery for a living is made to marry him, and she agrees to it to save her grandmother. She looks after him day after day, and what she feels for him turns into love. The man has been acting the fool the whole time. He is the heir to the group, and he has kept who he is hidden. After the wedding he gives his attention to her alone and spoils her. His stepmother has her own plan for the marriage. She wants the wife to have a child with the stepmother's own son so that the inheritance can be taken from the heir. The couple runs into opposition from the family, quarrels over the estate, kidnappings and schemes in the business world, and secrets about parentage come out as well. In time the two of them join forces and take their own revenge. A pregnancy report that turns out to have been forged is what finally clears up the misunderstandings between them. Almost at once the grandmother begins pressing them to have a baby. The wife holds that a real marriage needs time, understanding and closeness before that.
