Looking for That Person of Mine

The young man thought he had found a high-paying job, but he didn't expect to find a job as a terrorist! After an explosion, he traveled through time and entered a strange ancient world. The voice that claims to be the maintainer of the world speaks in his mind, asking him to find someone who truly loves him in this world. If he finds someone, he can send him back to his own world. It's not difficult to find someone who truly loves you, but what would happen if you time-traveled me into a daughter's body?
