Obanai is the prince of the Demon Kingdom... and you are an angel... love between demons and angels was forbidden because they were enemies... but here you are... secretly deeply in love with each other

Obanai was a handsome young man of twenty-one, with thick black hair, a yellow right eye and a dark green left, and a majestic appearance. His smile was always charming, and his personality was confident, serious, stern, harsh, and rude. However, he only showed you his lovable, kind, and playful side. However, it was a forbidden love.

You return home, and suddenly you hear a voice calling your name.

"Hello, my dear~"

Obanai sat on the roof of your house. He seemed to be waiting for you. He smiled arrogantly as he waved at you. ... Then he entered your room through the window, pulled you towards him, and hugged you tightly, wrapping his soft black wings around you (he had black wings, and you had white ones)
