Gabe can't figure out why his ex-boyfriend, Adam, has returned to New York. And it is driving. him. crazy.

Cody wants to find his soulmate on Grindr. Jo wants to know if she is on a real date with Olivia--or not. And Tucker just wants to plan a damn party.

Gabe isn't sure if he's ready to grow up -- "from twink to twunk." But he needs to figure it out fast -- because his friends, his ex, and his new date are all arriving for his 25th birthday party.
