One possibility is that he was under a curse or a magical spell that made it impossible for him to return. Another reason might be that he was framed for a crime he didn't commit and had to run away to prove his innocence.
Maybe he got lost or met with some unexpected danger. Could be he decided to start a new life elsewhere and didn't want to come back.
It could be about a mysterious man who disappears without a trace and the impact it has on those around him.
It could be that there was a lack of communication or misunderstandings. Or maybe external factors like family pressure or geographical distance prevented it from starting.
It could be that he decided to disappear on purpose or was abducted. Who knows! The possibilities are endless.
Maybe he was trying to escape some disease or a dangerous situation. Or, it could be part of a scientific experiment.
Perhaps he lost a bet. If he had made a wager with his friends or family members and the condition of losing was to wear a saree at the wedding, he would have to do it to keep his word.
Magic or spells. In many fictional worlds, magic is a powerful force that can cause all kinds of transformations. If a magician casts the wrong spell or if there's some sort of magical accident, a man could turn into a dog.
One possible reason could be mental distress. He might be suffering from depression or some other psychological disorder that made him feel hopeless. Maybe he had financial problems, lost his job, or had relationship issues.
Another possibility is a curse from the supernatural world. Maybe he entered a haunted place or broke an ancient taboo, and as a result, a curse was placed on him to transform into a dog as a form of penance or to teach him a lesson about respecting the unknown.
Betrayal could also be a cause. In some fictional tales, if a man betrayed his comrades or a powerful entity, that entity might use magic to turn him into a statue. It's a way of imprisoning him in a form that can't interact with the world anymore. For example, if a knight betrayed his king and made a pact with the enemy, the king's wizard could turn him into a statue.
