Su Nian, a seasoned photographer and devoted admirer of good looks, suffers a double betrayal and drunkenly marries a handsome stranger.
She never expected that her “bargain husband J” would be Jing Zhuo, the “stuffy, strict, terrifyingly fierce” big brother her best friend had warned her about, the living King of Hell!
[Ding! Your marriage has been activated. Please enjoy the exclusive affection from “J”!]
Online, her mysterious husband “J” is rich, considerate, and always ready to grant her every wish. He gives her a giant diamond, builds her an art gallery, and spoils her rotten.
Offline, her best friend Zhang Hening constantly complains: “My big brother is an iceberg! He has no sense of romance! Marry him and your life is over!” Confused by the [extreme contrast], Su Nian wonders whether her friend is seeing him through rose-colored glasses or whether her husband has a split personality.
When the gentle, thoughtful “second brother of her dreams,” Zhang Heyu, appears, love-triangle showdowns keep erupting, and Jing Zhuo's jealousy spills over! Su Nian is gradually caught in an emotional whirlpool. She's fallen for the gentle “J” online, yet she can't ignore the [secret allure] Jing Zhuo has in person.
Then, during an accident, Jing Zhuo is forced to reveal his identity while saving her. “Niannian, don't be afraid!” The face identical to her best friend's big brother calls her by her pet name, shattering every disguise in an instant! Her anger at being deceived, the truth of her feelings, and his [long-planned secret love] all surface at once.
She thinks it's a case of mistaken flirting, never realizing it's a [trap of deep devotion].
Only after every mystery surrounding his identity is uncovered does Su Nian understand: she didn't marry an iceberg, but a man who gave her all his tenderness and possessiveness.
Will she forgive him and run toward him, or walk away? Where will this wealthy-family marriage, sparked by “mistaken flirting,” lead?
