Sophie Xie works as a scientist for an aging research startup named Abyssinian Bio, while Martin Warwick is working in the academia researching the topic of aging.
They meet at a conference and hit it off, beginning a long-distance relationship.
Two years later, they decide to work in the same city and Martin takes a job at Sophie’s company rather than stay in academia.
Over the years, their relationship suffers as Martin grows increasingly obsessed with finding a way to never age, while Sophie focuses on her career and the research itself.
Eventually, Martin’s behavior and his overly-ambitious mentality towards the topic of immortality gets him fired, and he and Sophie gradually grow apart before officially splitting.
The story is told through flashbacks as Sophie reflects upon her relationship with Martin as she prepares to give a keynote speech at a conference.
