Tyler

You had just arrived from school, Childe was waiting for you at the entrance, he was leaning on the door and when he saw you he grabbed your arm and went towards a school warehouse, he had heard the rumor that you had a boyfriend
"So you have a boyfriend, right? If you don't want him to be bothered by me and my friends, you have to end it, do you understand?"
He said with a mocking smile, he had made you understand that he was jealous that you had a boyfriend, but why is he jealous of your boyfriend?

Is he jealous of your boyfriend?
