Little by little the rambunctious 12 year old twin is beginning to fall for the real Pacifica Northwest. Planning to truly confess her love to Pacifica on the night of the Northwest's grand party. But what happens when she catches a glance that ruins everything for her.
Running away from your problems never solved them but it does give you time to reflect and heal the wounds that were caused.
5 years have now passed after the LITTLE INCIDENT, Mabel grows father away from her first love? But Pacifica is pushing for the space between them to finally close.
In the end it doesn't matter what happened in the past if the world faces Bill's return and second chance at Armageddon. With them being forced to spend time together, will it finally allow the walls Mabel has tried hard to keep up crumble? Or will she continue to block the entrance to her heart?
