Searching and Searching for My Beloved

The young man thought he'd landed a high-paying job, but it turned out to be work for terrorists! After an explosion, he transmigrated to a bizarre ancient world. A voice claiming to be the world's caretaker spoke into his mind, telling him to find someone in this world who truly loved him. Once he did, he would be sent back to his own world. Finding someone who truly loves him shouldn't be hard, but what do you mean you've transmigrated me into a girl's body?
