My Dear Duke(BL)

On his 20th birthday, Asher's mother revealed a shocking truth he had never anticipated. After disclosing the secret, she passed away, leaving her final blessing for him. Asher found himself utterly alone, bewildered about his identity and anxious about his future. What did she say? - Was he someone special? - Someone people would pursue? She told him that he belonged to a rare and extraordinary race called omega, where men could bear children. Was this real? Initially, Asher staunchly rejected his mother's confession. But eventually, he had no choice but to accept it as the harsh reality. If he truly belonged to such a rare race with a unique body, did he have to spend his entire life hiding to avoid being captured and becoming someone's plaything? Was that the only way to prevent meeting the same fate as his father? Why was he even born like this? All he wanted was a peaceful life. So, if he just forgot he was special and lived like a normal person, it wouldn't be as dangerous as his mother warned, right? People wouldn't notice. After all, it had been a long time since anyone last saw an omega, and they might believe omegas no longer existed. At least, that's what he thought... He believed people might have forgotten about his kind, and he wouldn't face any issues in the future. Whether he was special or not, he still became a target. When he was kidnapped and sold as a slave, he regretted ignoring his mother's final advice. "Don't trust anyone easily. Your safety is in your hands, and protecting yourself is your duty." He could only blame himself and brace for the worst if his unique identity was revealed, fearing he would meet the same end as his father. However, fate gave him a second chance along with a surprising twist that transformed his life for the better. Asher was rescued by the so-called 'bloodthirsty monster' duke and brought to his mansion to care for his spoiled 10-year-old sister who demanded Asher comfort her. Just babysitting this adorable little girl. He was safe. His secret remained secure within him. Thanks to the chaotic brother and sister, Asher's life slowly took new turns and continued almost without obstacles... until a certain point. The surprise? The duke had a mysterious illness with no known cure. Not long after Asher discovered it, he turned out to be the perfect remedy for the duke's condition. But how? - Remember? He was 'special'! Where would his uniqueness as an omega lead his life? What mysteries would he encounter with this duke seeking comfort from him? Would the duke's mysterious illness ever be healed? How would their story unfold to a perfect happy ending with love unexpectedly blossoming between them? Note: This story unfolds in a historical timeline. Similar to omegaverse, but not the same universe. Involves magic, revenge, dukes, royal families, curses, spells, heats, ruts... (The book cover is from Pinterest. Respect to the artist.)
