Qiao Anhao and Lu Jinnian had secretly longed for each other for thirteen years, and now that there’s a possibility for them to be together, even though the circumstances may be unconventional, neither one can refuse their inner desires any longer.

Hurled into a false marriage, Qiao Anhao treads carefully towards the cold and reclusive Lu Jinnian, but after years of near-missed opportunities and deep misunderstandings, how could their last shot at love possibly run smooth?

“Nation Husband” is a Korean term awarded to a man who is perfect in the eyes of the public – an ideal husband.

D-list celebrity Zhong Ruanxing had been embroiled in controversies over her sultry figure ever since her debut. Smear campaigns and malicious rumors clung to her like a shadow. Years of oppression from higher-ups and sabotage by rivals made it difficult for her to shake off her reputation as a femme fatale, severely hindering her career.

Song Jingxing, CEO of the prestigious Song Group, graduated top of his class and stirred up storms in the business world with his capabilities. An aloof presence at the pinnacle of power, his interpersonal relationships were a mess, with even family keeping their distance. People loathed his attitude.

A freak accident caused these two very different people to swap bodies.

What they thought would be an arduous ordeal turned out to be an unexpected boon. Each found they could easily resolve issues that had plagued the other.

The celebrity living the CEO’s daily life: Greeted his family affectionately, treated subordinates with care, gave employees benefits, complimented his secretary’s new hairstyle—starting the day with vigor!

The CEO as celebrity: Trampled over rivals, tore apart enemies, sent lawyers after antis. Whoever dared provoke him would die! The CEO was whipping the entertainment industry into shape!

Much later, netizens posted:

[Who is Zhong Ruanxing’s backer? Her resources are too good now. From nobody to A-lister, whose thighs did she hug to get here?]

Online influencers hurried to speculate about the magnate behind Zhong Ruanxing.

Until the famously aloof CEO of the Song Group responded: I’m pouring resources into my own girlfriend. Got a problem with that?
