I think it was the act of the shaitan that comes between the two brothers, and now they are separated and both are on their journey, It was the heat of the moment that the hard words came out of the mouth of one brother, that hurts the other one and due to this he decided to leave the house without even telling him.
But there is something which is always in the blood relations, that something is love and care that both the brothers have for each other and after the disappearance of one brother, one started to get worried about the other brother.
and now both the brother are living their life, they both got married and both of their wives got pregnant as they planned. One gave birth to a beautiful daughter and the other gave birth to a beautiful son.
I'm pretty sure of it that one way or another, they both will meet one day and their kids will marry each other. their destiny will be to become together again. Don't know how many nights it will take.
