More than that <3

Y/n is a 18 year old student who has been friends with lizzie since they were 5 and they grew up on the same street. Y/n is out to everyone they know as a lesbian. One day at the end of summer after spending a few months apart, Lizzie and Y/n spend the evening together and have a sleepover where something happens that wasn't expected.
Y/n spends the next few months trying to figure out if what happened had a reason. She tries to ask lizzie, but will it be too late to ask her?...
