Kaixo is the strongest god at the other world, but it turns out he fell in love with a human, he can't let go of her...

One day, when you're 12, you got a seal pupil from the god named Kaixo. The articles said if someone got a seal pupil on their eyes, it means they have to die at age 20 or 18. But the god named Kaixo put the seal pupil and you have to die at the age of 18. Once you sleep, you've got a dream. You saw the god named Kaixo that put the seal pupil on your eyes.

Kaixo : oh hey, my bride.
