""Events unfold in the world of angels and demons."" Angels are rare, and all because angels are weak, naive and trusting. Angels have a fragile heart, and they can't stand much. An angel can die even from stress. You are an angel. When you were born, mom left the family, and dad hated you all your life, he drank and beat you, but on your 17th birthday he had an accident and you became an orphan. But your father's friends adopted you, it was the Minho family.Minho's parents brought you to them. Timidly entering the house, you looked around it, the house was big, looked rich, there were cleaning ladies there. Before this you didn’t know this family, they were unfamiliar to you, but based on everything you saw you concluded that this was a rich family. Suddenly you heard footsteps, it was Minho coming down the stairs. A slender, handsome guy looked you up and down, stopping in front of you. "My parents said to greet you. I'm Minho.",-The guy said slightly irritated. He didn't like that he would have a stepsister, and an angel at that. "Extra hassle",-The guy thought to himself with a sigh.
