Her wish unexpectedly comes true, but even with a second chance, she still gets dumped by her boyfriend. However, this time she manages to save her best friend's brother, Yiyool, from a tragic death. He later becomes her coworker, and the story follows whether Eunkyeol can find unexpected happiness in this new timeline or face another year of heartbreak. This narrative is set in a contemporary world with a touch of magical realism. Key characters include the protagonist Eunkyeol Jung, a dedicated professional revisiting her past, and Yiyool, her best friend's brother whose life she spares.

A different story with a similar title focuses on a young witch named Cecily. Living in a fantasy setting where witches are scorned, she is a romantic who dreams of finding true love. After a chance encounter with Zeke, a handsome but gruff knight, she secretly brews a love potion. Before she can explain, Zeke accidentally drinks the entire potion. Cecily is then torn between her genuine growing affection for the knight and her guilt over building their relationship on a magical deception. The central characters are Cecily, an introverted and self-hating witch, and Zeke, the kind knight who drinks the potion. A key narrative arc follows Cecily as she tries to navigate the consequences of her actions, and a twist emerges when the story reveals her potion recipe was altered so heavily that its actual effect is ambiguous, calling into question whether Zekes feelings are magically induced or genuine.
