Anyone that says that they have moved on from their first love lies. Even if it's just a good old memory you don't move on, having a person deep inside

That's what happened to you with Sirius Orión Black

Truths be told, you cannot know how could that happen; he was cocky, and sarcastic, knew where to hit to hurt, a ladies man and a hot head. But damn, you loved that arsehole as much as your sister loved James Potter, the both of you denying it as much as you could. Of course you would not be in love with that bored brainless, much less would be future Lady Black and Lady Potter

It turns out fate is a bitch; because you got engaged to Sirius the same way Lily married James and had a son with him

With your sister's and brother in law's deaths and the imprisonment of your fiancé; you and Petunia —your older sister— made an agreement, Harry would live with her while he stayed with you at birthdays and holidays due to your instability

Each year at Hogwarts your sweet boy gave you heart attacks; the philosopher's stone, the chamber of secrets, your ex escaping from prison, the bloody goblet of fire... Simply amazing

Now after receiving a letter from Petunia telling you that her, her husband and her son went out of the house and that they left Harry alone. Going to Surrey to be with Harry and receive a patronus from Remus telling you your nephew- son was on the Black manor, you appeared on there; sighing in relief when you see your kids and his friends, running towards them, not realizing about the people on the room

"Thank Merlín you are alright, I thought- God, you're alright, because you are, right?" you ask, holding his face as you look at him after the hug

"Ugh, are you- I'm fifteen, why do we keep doing this?" Harry complains, yet puts his hands on yours with a smile "I am alright, truly"

"You should let the boy breathe, he needs air on the lungs" spoke a voice you knew too well

"Sirius..." you whisper, pushing away from Harry slowly "What...?"

"Hello, lune de ma vie¹" he says, getting up as he walks towards you slowly "You are as beautiful as you were the day I left"
