My Dear Duke(BL)

On his 20th birthday, Asher's mother confessed something he never expected. After the truth was revealed, she died giving her last blessing to him. That's when Asher found himself all alone, confused about his own identity and worrying about his future.What did she say?-He was someone special?-Someone people would come after?She said he was coming from a very rare but also a very special race called omega where men could get pregnant. Was it real? At first, Asher strictly refused to accept his mother's confession. But in the end, he had to believe it. Because it was the bitter truth.If he was really coming from such a rare race, and had such a special body, did he have to live all his life hiding so he wouldn't get caught and become someone's plaything? Was that the only way to avoid getting the bad ending his father got?Why was he even born as someone like this?! He just wanted a peaceful life.So, it wouldn't be as dangerous as his mother said if he just forgot he was special and lived like a normal person, right? People would not notice. Alas, it's been a long time since people last saw an omega and they must be believing no omega exists now.At least that's what he thought...He thought people might have forgotten about his existence and he would not have to face any problems in the future. Whether he was special or not, he still became a target.When he was kidnapped and auctioned as a slave, he regretted ignoring his mother's last advice.“Don't trust anyone easily. Your safety is in your hands and protecting yourself is your duty.”He could only blame himself and expect for the worst if his special identity was to get revealed and meet the same end as his father did.However, his fate gave him a second chance along with a huge surprise which changed his life for the better.Hopefully, Asher was saved by the so-called 'bloodthirsty monster' duke and brought to his mansion to babysit his spoiled 10-year-old little sister who threw tantrums declaring she wants Asher to pat her head and comfort her.Just to babysit this adorable, little girl. He was safe. His secret was also secured within himself.Thanks to that chaotic sister and brother, Asher's life slowly took new turns and continued with almost no obstacles...till some point.The surprise?The duke happened to have some kind of a 'strange' illness that had no cure.Not long after when Asher discovered it, he ended up becoming the perfect cure for his illness.But how?-Remember? He was 'special'!Where would his specialty as an omega lead his life to?What kind of mysteries would he have to encounter with this duke wishing comfort from him? Will the duke's 'strange' illness ever get healed?How would their story flow to that perfect happy ending with the twist of love landing in the middle of their 'just a deal'?
