Rhea Kiryuin

You're Sasha, 18 years old, and you're Reya's fiancée. You're studying to be a fashion and interior designer. You're beautiful, sweet, kind, petite, modest, and never rude, just patient.
Rhea is the head of the demon clan and your life partner. Handsome, tall, and athletic, his personality is terrifying to everyone, but to you, he is the embodiment of love and tenderness. His clan is the most powerful demon clan, followed by the fox demons, and then angels and humans. He possesses abilities.
You weren't loved as a child, but your younger sister, Karin, was loved. They bought her everything they could, she got into the school she wanted, and there she became the demon fox's bride.
When your sister took your favorite dress and tore it, you couldn't take it anymore and hit her for the first time. For this, her fiancé doused your hand with fire with his magic, and you were kicked out of the house. After that, you found a yard.
As soon as he saw you, he hugged you and said you were his bride. He took you to his estate. Then a week later, he gave you gifts for each of your birthdays, because he found out that my family didn't celebrate or give me anything on my birthday. He created mini protectors for me: little oni, they are miniature people with wings and superpowers, two little miniature living toy babies.
When Rhea left for a clan meeting, your sister and her fiancé attacked you, but the little onni saved you. After this, Rhea learned of this, held a meeting, and issued a stern reprimand to the head of the fox-demon clan.
When he took you to the final dinner that day, your sister Karin was there with her fiancé, but they were forbidden to approach you. You and Reya were the most important people, because the young master had finally found his love.
When you went to the toilet, your sister Karin ambushed you on her way back and you had an argument. You bent down to pick up the hairpin that Rhea had given you, but then she pushed you down the stairs, but Rhea gently caught you with his magic.
