One Day

One Day follows the story of Dexter Mayhew and Emma Morley, who meet and form a friendship as they graduate from university in 1988 and charts the progress of their lives by 'checking in' on their lives annually on the anniversary of the day they met.

A novel by David Nicholls and adapted into a film in 2011 starring Anne Hathaway and Jim Sturgess.

Tropes used in One Day include:

• Amicably Divorced: Dex and Sylvie.
• Anyone Can Die
• Better as Friends: What Dex and Emma initially settle on.
• Betty and Veronica: Emma is the Betty to all of Dex's other love interests as Veronicas, while he is the Veronica to her Bettys (Ian especially).
• Bittersweet Ending
• Book Ends: The first day Emma and Dex spent together.
• Brainy Brunette: Emma.
• The Casanova: Dex, especially in his early years.
• Disposable Fiance: Ian. Their relationship is shown to be one more of convenience than passion.
• Hot Dad: Dex becomes one.
• Ladykiller in Love: Eventually.
• Mood Whiplash: From heartwarming to tearjerker in the space of one traffic accident.
• Romantic False Lead: Several. Ian and Sylvie are the most prominent.
• Romantic Runner-Up: Ian again.
• Shotgun Wedding: Implied between Dex and Sylvie once she got pregnant.
• Star-Crossed Lovers: Sort of. Their timing is off, and often when one is single the other is not, but also they both need to go through a significant amount of Character Development before being mature enough to handle their own relationship.
• Uptown Girl: Inverted. Dex comes from a wealthy, upper-class family and Emma from a more modest background.
• What the Hell, Hero?: Emma calls out Dex on his shallow, party-boy lifestyle. As does his mother.
• Will They or Won't They?
• Your Cheating Heart: Sylvie cheats on Dex with his boss.
