My Girlfriend's Sister
Octavia has met her ideal partner on a dating app. Parker is everything she's ever wanted in a man-handsome, kind, and sensitive. Things are going so well they decide to move in together. Everything is perfect until the day Octavia receives a text from her free-spirited and irresponsible sister. It seems that "Hurricane Haley" is blowing into town and needs a place to stay. Chaos ensues as soon as Haley makes her presence known. Poor Parker doesn't stand a chance.
