Forced to marry in her younger sister's place, Song Nuannuan becomes the bride of Jiang Jingcheng, the comatose heir to the powerful Jiang family.

Everyone is convinced that the plain, unattractive Song Nuannuan won't survive even a single day in the Jiang household. Instead, she not only thrives but undergoes an astonishing transformation. The "ugly duckling" blossoms into a breathtaking beauty. The so-called good-for-nothing reveals herself to be a brilliant hacker and a gifted painter.

Then, against all odds, Jiang Jingcheng—the man who was expected to spend the rest of his life in a coma—suddenly wakes up.

As the world watches with envy, Jiang Jingcheng wraps an arm around his wife and declares with unmistakable pride:
"Jealous? She's mine."
