My Boss Is A 1000Years Old Demon Lord|| Muzan X Mitsuki|| Kimetsu No Yaiba
***
So this is basically an alternate story about Muzan and the heroine I made up, Mitsuki.
I'm so sorry for any mistakes, cause I suck at writing.
***
Both of them used to know each other when they're young. A 15 years old Muzan fallen in love with a 514 years old demon queen, Kazuki Mitsuki. However his sickness and her demon identity, they couldn't last long, and that's when Kibutsuji Muzan fell into despair, knowing that the love of his life left him.
As years past, that despair turns into rage and hatred, and slowly, the caring lord turns into a vindictive and malevolent demon progenitor.
Years, decades, centuries....
21st century
Muzan and his family took a business trip to Hollywood because of an agreement of partnership. Two companies collided into one.
Muzan, now known as Tsukihiko, is the Chairman of the company. However, the other company has a celebrity star, Miki, last known as Kazuki Mitsuki. Muzan never knows she's the girl he hates because of her name and appearance has changed, and the same goes for Mitsuki.
Kazuki Mitsuki, loathes men. She thinks them as pigs. So, where's the fun of not showing them who's boss? She started to have her playerish ways.
Two, totally personality changed demon, came from different worlds...
However, the only thing that similar is the hatred they had with one another.
If you say impossible for them to fell in love, think again
