She grows from a supportive friend into someone who tests the boundaries of their relationship, writing a formal contract to navigate an unusual arrangement. Her evolving feelings for Jonah add complexity to her practical mindset.

Jonah is a carefree, party-loving guy whose world tilts when he’s diagnosed with testicular cancer and learns he may not be able to father children. He grapples with fear, denial, and a stubborn desire to keep his party life intact. His relationships with Stevie and Becky reveal his capacity for vulnerability and growth as he confronts mortality and desire.

Gus is the loyal but sometimes oblivious friend who helps run the party enterprise. He provides steady support for Jonah and Stevie but remains largely unaware of how their evolving relationship is impacting the trio. His practical optimism anchors the group as they navigate risky decisions.

Becky is the woman who knows Jonah well but refuses to view their connection as casual or fleeting. She represents boundaries and a restraint that clashes with the impulsive plans around fertility and relationships. Becky's stance creates tension within the group and challenges the protagonists’ assumptions.

Ava is Jonah’s ex who appears initially reluctant to be contacted again but ultimately becomes a potential option to carry his child. Her pragmatic approach contrasts with the emotional pull of the other relationships, highlighting the film’s theme of choosing a path forward amid difficult circumstances.

Dr. McKenzie is the medical authority who informs Jonah of his cancer and the fertility implications. His explanations drive the ethical and practical decisions the characters confront, including the possibility of sperm banking or alternatives for fatherhood.
