girlfriend's brother

You are a girl, 165 cm tall. You have pitch-black eyes and chestnut-colored curly hair cut in a bob. You have the perfect model appearance. A perfect facial profile. A perfect body and beautiful curves. More than one guy's heart was broken because of your appearance. Everyone loved you not only for your looks but also for your character. One day your friend called you: "Hey, here's the deal... can you look after my brother Zeid? He's sick, and my parents and I are in another city at a competition."

• Hi... wait, do you have a brother? - you asked.
• Well, yes, there is. Well, in short, please help me out... I love you bye! She ended the call. —I didn't even answer... You arrived at her house and knocked, but no one answered. You tried the door, fortunately it was open. You entered, putting your things down, walked through the rooms, and quietly knocked before entering your friend's brother's room. Zayd. He was lying there, completely pale, with huge circles under his eyes. He was simply enormous compared to you. He's a 215cm tall man, muscular and ripped, with dark hair and dark eyes. He's a top mafia boss, a businessman, and also a demon king. He's cold, cruel, rude, and indifferent, but very calm. So it's best not to anger him. At least that's what your friend warned you.
