Dating Remus Lupin as Sirius younger sister would include
Context: You were 3 years younger than Sirius, 2 years younger than Remus and 1 year younger than Regulus (in short you were in the first year while Remus was in the third year at Hogwarts). The beginning of the headcanon takes place when Y/N was in the fourth year and Remus in the sixth year.
- The Marauders already had an idea of what you were like, because Sirius talks about you a lot (Y/N is his beloved little sister <3), but they didn't think they would completely love you once they met you (even more Remus, he didn't thought he was going to fall in love [didn't even consider falling in love] with the younger sister of one of his best friends)
- You and the rest of the marauders only had real contact with you after you started dating Remus (this brought you and Sirius a lot closer)
- When you guys get closer (as friends) Remus didn't know why you went to Slytherin, since you're so sweet and polite and kind. As time passed, he saw more clearly why.
- You who took the first step, and asked him out
- Studying together in the library
- Meeting in the monitors' round
- You being Head Girl Slytherin (Remus is head boy Scout, so he's your boss)
- Sirius finds it strange, but it's not something he bothers about
- James biggest fan of yours
• When you fight James always, ALWAYS helps you to reconcile
- Regulus is very bothered by this, but he didn't intervene because he knows you are happy
-He is quite jealous because he is so insecure because he thinks you don't deserve to be forced to deal with his furry problem
- Remus doesn't let you hear swear words, so whenever he says one near you, he covers your ears
- Shares his chocolates with you
- You buying him expensive chocolates
- You two reaching an agreement
• White chocolate is not chocolate
- Remus loves to hug you from behind and smell your neck (your scent soothes him)
- When the moon is full, he gets very stressed and won't let anyone touch him but you
• The rest of the marauders already complained about it, but then Remus just gave them the middle finger while hugging you
- The first time you sleep with Remus in the boys' room you and Remmy are woken up by James snapping pictures of you with a camera
• Remus covers his ears “What the fuck James. What is the need?”
• “The need is for me to keep memories of my favorite couple, so that in the future I can show them to my godchildren”
• Remus blushes at the mention of you and him having a child
- Remus already wanted to break up with you because of his furry problem, but you didn't let him and you lectured him
- Sitting on his lap reading a book together
- He loves when you take care of him after the full moon (you make him feel very loved) <3
- He feels more comfortable making out
- Whenever someone is mean to him, his Slytherin side comes out and you humiliate the person with class
- You started eating at the Gryffindor table
- Taking care of his wounds
- Regulus stopped bothering, he even ships
- You live in the Gryffindor common room (honestly no Gryffindors bother [some don't even know you're in Slytherin, because you only wear Remus' clothes])
- You, Sirius and James like retards singing music at dawn
- Test? Remus helps you study. Magic history writing? Remus helps you. Tasks? Remus helps you
• Remus helps him a lot, in exchange for all his love for our beloved boy
• Interrupted by the boys =p
- Him reading to you when he's having trouble sleeping
- Sometimes he treats you like a child, but he knows that this child can turn into a scary beast
- Enjoying this year, a lot as it will be his last year at Hogwarts
- Remus joins the order of the Phoenix
- The war outside the school is terrible
- Remus is worried about you because of your parents (not only him, but the rest of the marauders [Six mostly]
- His parents still haven't found out (thanks to Merlin)
