It was after the War Of Hogwarts, just 3 hours after the War, and you wanted to say that you loved Neville for so long, you even wanted to say it to him After the War, like right now..
But right now you were at the Black Lake with him, your bestfriend, Neville Longbottom, you were in love with him but he was already with someone, so you didn't do or say anything, fear of being rejected because he's with someone and happy.
You know you could never ever have him.. he was happy with his girlfriend so you were happy too. You were looking up at the stars like him, that was admiring the stars.
You: "You know.. sometimes we love people like we love the stars.."
Neville look at you interested and curious.
Neville: "Really? How?"
You look at him before looking at the stars and you sigh.
You: "We love them knowing we could never have them.."
You were aiming this sentence of him, like he's a star in the night sky and you someone that could never have him knowing he's too far away..
