Riley is upset to hear that her father is marrying someone.
Until she meets Mia..
Who of course is, her Stepsister?
I would be pissed too, to be honest it kinda sucks because you love your real mother and it has to hurt to see your dad move on and get married😟
Sabotage the wedding! Salt in the cake. Juice on the dress. Dog eats the tux. Invitation never sent. *grins evilly* I'm in.
