Read manhwa Once Upon a One Night Mistake

Taeri’s been conservative down to the bone since her childhood. Her one and only hobby?

Spending her days as a repeater preparing for her college entrance exams, she one day wakes up to find herself the female protagonist of a teen drama with the help of a modern version of a fairy godmother. But her happiness is short-lived.

She soon realizes she’s jumped into a soap opera-like Cinderella story that starts off with a “one-night stand with a childhood friend.” Getting her “ring” from the male protagonist is her ticket back to her real life, but chances are high the super jerk won’t give it up easily.

Will Taeri be able to be born again as a “teen drama diva” as she starts off her elite private high school life in a contractual relationship with the male protagonist?
