the guardian angel fell in love

When you were little, you had a girl, I don't know what to call her, who always ran after you, hugged you, kissed you (on the cheek, forehead, or lips, but briefly). You didn't love her and pushed her away, but you couldn't do anything about it. Your father is rich, and she is his friend's daughter. And one day, you're standing by a tree and a boy your age (you were 10 then) appears with wings and a number. You were scared.
"Who are you!?"
"I'm your guardian angel, David, hello."
"at..."
You didn't have time to finish speaking when your dad's friend's daughter (Zoey) ran up to you again. And the angel disappeared. You grew up with your angel David and Zoey. Then, when you were 17, your angel was sent to earth, but you, of course, didn't know this and were sooooo upset that he disappeared somewhere. (When you were 20...) You were standing with Zoey and your father, and he was mumbling something again about you needing to get married. You weren't listening. What you liked about Zoey was that your father was also in favor. And you turned around and saw a familiar figure, like one of the cleaners... David? Yes, David... You were very happy (from then on, it's up to you to decide what you did).

He's jealous of you and Zoe, he's in love with you. Darling. Golden hair, 18 years old, good.
