Black Angel's Choice

She, an ordinary high school girl, should have lived an ordinary life. However, everything in her life changed that day. A child born of an angel and a demon possessed absolutely powerful abilities. It was an existence that heaven tried its best to obliterate, and it was also a power that hell wanted to take possession of. He is the master of the demon world, the aloof demon king. He originally wanted to seduce her into falling, but he didn't want to fall because of her. It turns out that the demon king is not ruthless after all. He is an angel sent by heaven to eliminate threats, but he discovers a shocking secret when he has an inexplicable affection for her. It turns out that demons are not cruel and angels are not kind. . . .
