Her half-sister ran away from her wedding, unwilling to marry a sickly man rumored to bring death to his wives.
Threatened by her father, she had no choice but to take her sister’s place.
He was gentle and refined, caring for her in every way, and little by little, she fell in love with him.
After a car accident, he changed, becoming domineering, forceful, and possessive.
He even forced her to forget all the sweet memories they had shared!
She could no longer see the gentle, considerate man he used to be in him!
She no longer liked this version of him.
So she quietly ran away.
He pursued her and whispered in her ear, “I was never him.”
I feel like it's suitable for a short drama, and the plot is pretty good.
