Demon Slayer: I Reached the HE Ending After Rebirth

Ps: Two heroines, two enemies on both sides of human and ghost, two lines of love story Human Line: Wei Dianpo, a psychotic strong woman with a strong sense of justice Ghost Line: No procrastination, dark, arrogant, irrational, beautiful, strong and miserable female ghost [The heroine of Ghost Line is a pure evil, an absolute female villain who will not be whitewashed, and she will die in the end/Maybe there will be a happy ending in the extra chapter? Niwa Hisei chose to become a ghost hunter because his mother was killed by a ghost. He was killed by a mysterious and powerful ghost while performing a mission with his companions. After Nishoumu is reborn, he must protect his companions, break through the thick wall, and present a happy ending! Pain is nourishment. No matter how deep the pain is, the harm it brings to people is the same... I just want to erase the source of the pain... Is it ok?
