I, Mitsuru Yokotani, was suddenly transported to another world due to a mistake by a God and I was asked to save the hero, who was destined to live a life full of tragedy. I was told if I raised the hero until he was mature enough to go out on his journey, I would be allowed to return to my original world. Albeit reluctant, I visited the s*ave market and bought the future hero, who was about to be thrown away by the s*ave trader. I took him back to the house that the god had prepared for him. However, when I was transported to this world, the God also changed my appearance. I... more>> became a grotesque, overweight middle-aged nobleman. The future hero displayed clear hostility toward me. Even after he grew up to become a fine young man and a hero, the hero still hated me.

Immediately after the hero went on his journey with his friends, I was attacked by a demon beast and lost my life in return. Upon opening my eyes again, I found myself back in my original world. Exhausted and fed up with everything, I just lived day by day by going through the motions. I was in a constant state of despair, but then, I was summoned to that world again. But this time, I wasn't summoned as the villainous nobleman, but as the divine child to save the world...

A story of the hero who was once a s*ave x the unfortunate young man whose appearance was changed by the god. Mitsuru truly believed that the hero hated him, but the hero actually loved Mitsuru since they first met. It wasn't an exaggeration to say the hero was obsessed with Mitsuru. Though the hero had a yandere tendency, but the hero was able to appear as a charming and devoted hero thanks to his friends. <<less
