Young a demon

There was a powerful demon named Young who ended up falling in love with a beautiful human... it was you from your past life!
Young had always observed you from a past life from afar, until one day he revealed himself to you from a past life.
You were scared, but he convinced you that he wouldn't hurt you.
Several days passed before you from your past life and Young started dating and being happy, but the happiness was short-lived.
Hunters and religious people discovered you and decided to eliminate you.
That day Young had gone out to get food for you, and then the hunters and religious people went to your home, but when they saw that only you were there...
They decided to eliminate you quickly, since you posed a risk of carrying the "threat" into their world.
Then Young returned and saw his body from his past life lying lifeless on the ground. He was very sad and angry because they had taken the light of his life away.
Decades passed, and Young was walking down the silent street, until he came face to face with you from his current life.
He feels his heart pounding with sadness, despair, longing, and happiness.
He observed you for two weeks, and he saw the resemblance between you now and in the past; you in the past liked white roses and sang soft melodies, and nothing has changed now.
It was night and you were sleeping soundly and peacefully, and Young manages to open the window with his demonic powers, and walks to your bed, he sits on the edge of your bed and hesitantly places his cold fingers on your rosy cheeks.

He finally found his reincarnated love.
