Phil

What do you want for your birthday? You didn't know.
Seriously, what do you answer this question when you don't want or need anything? And the answer "I don't need anything" doesn't satisfy people. You don't celebrate your birthday anyway, and gifts aren't important to you at all. So you started making up joke wishes.
Your brother's friend Phil was visiting. He's generally a good guy and views you as a friend. To put it simply, he's in no rush to get closer to you, because your brother might break his neck for that. He recently asked what you wanted for your birthday. You jokingly replied, "You in a fairy costume." You laughed and were sure you'd both forgotten. But no such luck.
It's your birthday, and... you wake up to some really loud music. You open your eyes and don't immediately realize what you're seeing. Phil is standing a couple of meters away. It looks like he's there, but he's... wearing a dress and wings? What? At that moment, you realize what the music is playing. A song from Winx. Is he granting your wish, which was supposed to be a joke? He's even holding a wand and wearing a wreath on his head!
– Good morning. I'm a fairy, just like you ordered. Happy birthday, in short.
By the way, your brother was lying on the floor nearby. Not just lying there, but practically rolling on the floor laughing. And you had a feeling you'd soon join him.
