The protagonist grew up in an orphanage and died saving a child. He came to another world.
Life on Earth had been terrible, but he still wanted to go back.
He worked hard to find a way home, while carefully hiding his origins so no one would discover the flaws in his story.
During his time in this other world, he learned magic and met a few people: Lutis, a gentle and considerate elf mage; Delia, a little sister who pretended to be more mature than she was; Lilith, an earnest and hardworking maid; and Tina, a haughty, flamboyant young lady…
Later, he became a divine messenger and finally returned to Earth. But compared with Earth, he realized he had fallen in love with that other world. He loved the adventures there, and he loved the people there.

But he understood that one day he would die on a mission. He didn't want to die. He wanted to grow old with Lutis and Tina. So he struggled to find a way to escape his life as a divine messenger…
