remus lupin x oc; can you love me most?

PLEASE, READ THE DESCRIPTION.
"I would like him to smile at me"
[because Remus Lupin's smiles are the most precious things].
Loosely based on a fanfiction my sister is writing. Since she knows how much I love Remus, she created this character for me.
I hope the video will be self-explanatory enough but anyway, here's some background and the general idea for this character: her name is Cordelia Black and she's Sirus' youngest sister, born the year Sirius run away from home. After her parents and brother's death and Sirius' incarceration she was sent to live with the Malfoys, being them her closest relatives. She grew up with them but hers was a sad and lonely childhood. Her rooms were set in the wing opposite to theirs and she mostly had the company of Dobby. Sometimes Narcissa comes to see her but she's too busy taking care for her own son to properly caring of her. She and Draco are on mostly mild terms (they're not close but neither hate each other) after all Draco is very self-centric and also getting his father's approval is top priority for him. Lucius, being Lucius, sees her only as a burden (and he's even more bothered because she was sorted in Gryffindor) and would like very much to find a way to get hands on her inheritance that she'll get when she'll become 17.
At 16 (HP book 3) she meets Remus who becomes her new Defence Against the Dark Arts teacher and she soon falls in love with him. They get closer because she's Sirius' sister and so he would like to know her. Nothing romantic happens though, she never confesses him her feelings and he's completely clueless about what she feels for him and even more clueless about his affection for her.
The turning point in their relationship comes in HP and the Order of the Phoenix. She's 18 now and surer of herself and her feelings so she decides to pursue him properly but we all know that Remus likes to run away so he'll not make things easy for her even though (or exactly because) he soon realizes that he's in love with her too. But in the end of course they get together.
If you're interested, I'll put here in the description the link to the story when it will be ready to be posted.
It will also feature other OCs, all my sister's creations. She put a lot of care and effort into them, so it'd be lovely if you'll give it a try.
