To make matters worse, Aiden will have to spend the wedding weekend with Max and his soon-to-be-husband at their lake house. So, rather than go alone, Max decides to invite his roommate's eccentric friend, Lance to pose as his boyfriend. But, in the days leading up to the ceremony, Aiden realizes the awkward tension maybe more than he can handle.
