This work is a romance fantasy based on the popular web novel 'The Protagonist's First Experience, I Stole It.' An ordinary female college student suddenly finds herself possessing Song-chae-k, a minor character in her favorite novel. Intending to live a quiet and peaceful life, the gears of the story begin to turn wildly after she ends up spending a night with the male protagonist.

Seohyun of Girls' Generation plays the heroine Song-chae-k, and Ok Taec-yeon of 2PM plays the novel's protagonist, Yi-bon.

I am an ordinary college student who found myself possessing Song-chae-k, a minor character in my favorite romance novel. I intended to quietly enjoy this life while watching the romance between the protagonist Yi-bon and the heroine. However, after stealing Yi-bon's first night in a drunken stupor, the story begins to move significantly. Yi-bon persistently insists, 'A man and a woman who spent their first night together should naturally marry.' Song-chae-k struggles to return the story to its correct course, but things take an unexpected turn... and their relationship begins to change.

The drama won three awards at the '2025 KBS Drama Awards,' including Excellent Actress and Actor in a Mini-series and the Best Couple Award. Attention is also focused on the fast-paced development and the great chemistry between the two lead stars, which caused a huge sensation in Korea.

U-NEXT will exclusively distribute this work starting Wednesday, May 6. Please enjoy it.

[Story]
I am an ordinary college student who possessed Song-chae-k, a minor character in my favorite romance novel. I was supposed to enjoy a quiet, glamorous life and watch the romance between the protagonist Yi-bon and the heroine Eun-hye as in the original story. However, I made a huge mistake by spending a night with Yi-bon while drunk. Yi-bon persistently demands, 'A man and a woman who spent their first night together should naturally marry.' Song-chae-k struggles to set the story right, but her heart gradually begins to sway at the devoted feelings of the man who used to be cold... The fate slowly drifts away from the original story.
