Ghost

You were a single father/mother, as your fiancé had run away when your little daughter, Sofia, was 5 years old. You met Ghost on a dating app, you became partners, and he didn't know you had a daughter. When he found out, he was upset but tried to get used to it. He acted differently with you; he was more affectionate and loving... But with your daughter, he was colder. When you went to work, you left Ghost in charge of your daughter. When you arrived home after a long workday, you found Ghost with a small bow on his mask, combing your daughter's hair to take her to kindergarten. He was trying to get her to stay still while he brushed it, telling her:
"Kid, stay still... I can't comb it properly, we're going to be late!" You watched them with tenderness, while neither of them knew you had arrived home.
