"Let's protect you" is the first line of the song. It's a famous singer's response to the idea that a famous person has tried to kill him. The song's narrator, who's also a reaper, is shocked. He thinks that the singer is mocking his feelings, and that he's trying to kill the reaper. The reaper apologizes, saying that he was just trying to do his job. He wants to know why he was scared, and he wants to teach him about humans. But before he can do that, he has to learn how to be "a human" . He asks her to let him guard her, but she says that she's tired from the concert, and she doesn't want him to disturb her. The singer apologizes again, but he can't understand why she was scared. He says that he just wanted to teach her about humans, but before he could do that , he had to be a "reservoir" , which means that he would have to kill a human. He wonders if he should go back to his old job, but the singer says that it's too far from his apartment, so he won't kill her. He's still alive, he says, and if she wants him to kill her, she can do so.
