Arthur Holly fell asleep like any other day. And he woke up like any other day. Except that he didn't wake up in his own body, but in a three years old one.
Arthur transmigrated into what seemed to be the same world he previously lived in, except in the past, before he was even born.
But everything changed the day of his fourth birthday.
For those who want to buy me a cofee:
