One night he met an old man, who told him that all marriages were destined and two people could become a couple only when their feet were tied by the same invisible red thread. The old man also told him that his future wife was only three years old at that time and wouldn’t marry him until fourteen years later. The young man didn’t believe him and tried to kill that three-year-old girl. But no matter how hard he tried, it ended up as the old man said.
