Male Lead: Tae Minhyuk
The second son of the Taesung Group. A man who lacks nothing—looks, height, family background, education, and career. Arrogant and brazen, he’s earned notorious nicknames like “mad dog,” “dirty mouth,” and “man-whore.” But the most provocative title of all? Polyamorist.
However, he’s finally met someone he wants to own—completely, exclusively.

Female Lead: Noh Yuwon
The second daughter of the Hanyeong Group. Honest and emotionally expressive, she falls for the dangerously infamous Tae Minhyuk.
Believing she can change his polyamorous ways with the sincerity of her love, she begins a relationship with him—only to end it after facing the cold truth.
Four years later, the thread she thought had snapped ties her to him once again… in the most twisted of ways.

Read this when:
You want to see an arrogant, unyielding man shaken to his core by love.
You’re in the mood for a dysfunctional “show window” couple desperately trying (and failing) to get it right.

Relatable Quote:
“Why is it okay for you… but not for me?”

Synopsis
※ Please note: This novel contains explicit language, morally questionable characters, and depictions of coercive behavior. Reader discretion is advised.

Noh Yuwon became the partner of Tae Minhyuk, a known polyamorist.
Because she believed—someday—his heart would change for her.

But as he kept introducing her to his new partners, one by one,
Yuwon realized: he would never change.
And so, she walked away.

“I can’t do this anymore, sunbae. This open relationship… it’s not normal.”
“You wanna end it? Fine. But you’re going to pay the price.
After you toyed with me and made a fool of me, you think you can just walk away like it’s nothing?”
“Toyed with you…?”
“You were the one who lied from the start. Not me.”

When they reunited after four years,
he was the same as ever—
No, worse. A beautiful but poisonous flower, bristling with deadly thorns.

“No matter how I look at it, no one compares to you.
Since both of us are bound to be sold off anyway, let’s just marry each other.”
“If it’s with you… would that marriage be open, too?”
“Yeah. Nothing’s changed.”

…It was revolting.
Just sitting across from him made her skin crawl.
Talking to a man this insane,
who didn’t even know he was insane—
was physically nauseating.

And yet, to avoid an even worse arranged marriage,
Yuwon ends up taking Minhyuk’s hand…

“Just stay quietly by my side.
Don’t go around acting like you’re something special.”

An open marriage that begins with an arrogant ultimatum.
What awaits at the end of this mad love?
