Ten months after the confrontation with Tom, Olive brings Adam to the biology building hallway to stand by the water fountain where they first kissed. She positions him precisely, teasing him to look “antagonistic and unapproachable,” and snaps a photo, savoring the symmetry.

Olive reflects on their summer together—hikes, ice cream, star-gazing on Adam’s balcony—and on her imminent start at a Berkeley cancer lab. Despite the coming workload and commute, she feels excited and grounded in their relationship.

They banter about Anh and Jeremy and whether the exact moment of their first kiss can be known. Olive insists it can; she consulted her lab logs from the Western blot she ran that night and set an alarm to match the minute.

As the alarm beeps, Olive steps into Adam’s space and he pulls her close. Familiar with each other now, they share the moment deliberately and tenderly. Olive leans to his ear and asks, “May I kiss you, Dr. Carlsen?”
