OH MY GOSH!
I am so sorry about the relationship confusion!!!!!
I will just explain.
Roxy and Liam were going to be a couple but decided to not do it because everything was a hot mess and Roxy had true feelings for Louis.
Remi and Niall were sort of together and at the concert were supposedly a couple but they never kissed and it sort of faded away. None of them were confident enough to keep it going.
I am SOSOSOSOSO sorry about the confusion, but hopefully this has cleared it up! :] Thanks for reading!
