Hello!! I have a book suggestions if you don't mind. I was about to write this book but abandoned it cause i couldn't write... So it's called "Exchange". It's about where Hinata is a angel and the harems are a demons. They were sent to earth to defeat the humanity/human kind. While, Shoyo was sent to earth to protect humanity/human kind. After meeting with Shoyou on a fight, they became obsessed to him.
And after a day, the harems original form, human like form(which is the original looks). If your wondering what they looked like... They all had long hair and they had a full black clotjes like a saint(i dunno...)
Luckily, Shoyo couldn't recognize them. And after a lots of days living together, they knew about each other very well. And Shoyo's time to go to heaven got near, which Shoyo got worried. He knew that the holy lor Zeus, the GREATEST god will punish him for not completing the quest he was given.
This punishment also can happen earlier but the punishment's 20%-50%. The day came as the harems revealed their identy but Hinata resisted on killing them, instead, he sacrificed himself so he could make the harems quest finished.(he used Sugawara's weakness and stabbed himself.)
But this isn't the end, Hinata was sent back to heaven but he was already aware of the punishment. He's punishment was that his heart will get gripped by the god whenever he goes to earth or to hell. Shoyo ignored it and went to hell to see the harems.
The harems were happy to meet him but they realized Shoyo was dead because Zeus already ripped his heart to ash which lead him to death. Slowly, Shoyo's soul fades since his existence will be cleared. Everyone cried, feeling so much emotions.
But it didn't end! They recantated to next world like the canon(but a harem). Thanks for giving the time and read all of my yappings.
