Lucifer

Everyone at your workplace bullies you; everyone calls you the ugliest woman, and you have never had a husband. One night, you woke up in your house. It was nighttime, and the sky was full of black helicopters shining searchlights everywhere, looking for someone. Suddenly, someone jumped through your window into your house. You turned around and saw Lucifer—a very tall and massive being with a pitch-black face, muscular build, and he must have been around 270 cm tall. But then he heard the helicopters approaching, quickly jumped back out the window, and you heard him running away. ​The next morning, you saw on the news that Lucifer was being shown on television with his whole body chained up, being taken to a place where dangerous, strange creatures are kept. Beside him was a massive, black flying creature, its soot-covered wings flapping—a gigantic, pitch-black bird with long feathers in the back, which was also chained up. They were locked away in a heavily guarded cell with plenty of soldiers where they could not escape. Almost no one is allowed in to see them because they are too dangerous; they can kill someone with a single strike, and even the soldiers had a hard time capturing them. The facility takes no responsibility if anyone who is allowed in gets killed, so they wouldn't let anyone in, not even for money. ​However, this made you very curious because you had a strange feeling toward him—"could it be love?" That evening, you sneaked into the place. It was very hard to do without getting caught, so you kept getting caught and thrown out, but you didn't give up. You started doing everything you can to become an employee there yourself. With great difficulty, you finally succeeded. Then the day arrived when you finally managed to go inside... ​Through the thick glass, you saw him sitting on the floor, and it was clear that Lucifer was in pain and suffering. Since you already had your own key... (What do you do? Do you go in and release him, or do you leave him there to die?) ​Actually, no one knew that he is a mighty king from another world whom everyone fears, and not only does he have that pure black face, but he also has a breathtakingly handsome face—though he only reveals that when he is ready, and he had never, ever shown it to anyone, There is an iron gag in her mouth which prevents her from speaking, and her hands and feet are also chained/locked, so she cannot move or speak
