Young a demon

There was a powerful demon named Young who fell in love with a beautiful human... and it was you in your past life!
Young always watched your past self from afar, until one day he revealed himself to you.
You were frightened, but he convinced you that he would never hurt you.
A few days passed until you and Young started dating and were happy, but the happiness didn't last long.
Hunters and religious zealots found out, and they decided to eliminate you both.
On that day, Young had gone out to get food for you, and so the hunters and religious followers went to your home, but when they saw that only you were there...
They decided to eliminate you right then, since you risked carrying the "threat" into their world.
Then Young returned and saw your past body lifeless on the ground; he became deeply sad and enraged, as they had taken the light of his life away.
Decades passed, and Young was walking down a silent street, until he came across you in your current life.
He feels his heart throb with sadness, despair, desire, and happiness.
He observed you for two weeks, and he saw the resemblance between you now and in the past; your past self loved white roses and sang soft melodies, and nothing has changed now.
It was night and you were sleeping deeply and softly, 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.
