Hao Zi Qing (Note: This appears to be a Chinese name rather than Japanese text, as these characters are not in hiragana or katakana. The translation represents the romanization of the name.)

Nan Haoyu (南浩宇), who belongs to Nanfeng Seiin (南峰清雲) in the Heavenly Realm, is the biological son of the current sect leader, Nan Kanryu (南燗流), and has been appointed as the next sect leader. Upon hearing this news, people from other sects headed to Nanfeng Seiin, each bringing their top disciples. Nan Kanryu created an opportunity for the top disciples from each sect to study together, hoping to nurture more outstanding immortals. There, Nan Haoyu meets Hei Zisui (黒梓睿) from the Kokuran Gate (黒嵐門) in the Demon Realm—a person who is the complete opposite of himself. Although it was for the disciples' growth, an exchange between the Heavenly and Demon Realms took place, and among them, Nan Haoyu and Hei Zisui proved to be exceptionally talented. Nan Haoyu was exasperated by the free-spirited Hei Zisui, who kept him on his toes. However, during this time, demons—who belonged to neither the Heavenly nor Demon Realms—appeared in the human world. The demons included four high-level ones: red, blue, black, and white demons, along with numerous lower-level demons who attacked humans and committed misdeeds in the human realm. Learning of this, the sect leaders of the Heavenly Realm and their disciples head to the human world to exterminate the demons. When Nan Haoyu and Hei Zisui discover that the Demon Realm was involved behind the demons' rampage, they act together to uncover the truth. It is forbidden for those of the Heavenly and Demon Realms to be bound together. Yet these two, contrary to such teachings, are drawn to each other... In the end, an unexpected development awaits. A fresh take on a Chinese bromance novel that no one could have predicted. A Chinese bromance set against the backdrop of the Chinese martial world—we hope you will enjoy the story of two beautiful men whose relationship evolves from mutual respect and admiration to love. We would be grateful if you could be lenient with this story, as the author is not very familiar with ancient Chinese language and historical background. m(_ _)m
