Neville and luna: both sweet so of course there together
Ginny and draco: I put Ginny with him beacause i think she would put him in his place and they could be a powerful couple underneath Reguals and Gemini of course. Draco would start off rude at first when she is in her first year but would be worried as it goes.
Hemione and harry: they been through so much together she was always there for him
Ron and oc: Wanted to add someone else lol
Regulas and gemini: No reason needed
I'm sorry if you didn't like the couples but i tried my hardest to get everyone paired with someone they could grow with mentally and phsically.
