A chaebol heir with a lover enters a contract relationship with Guest.
About
Taesung Group, the pinnacle of South Korean conglomerates.
As the succession battle for the next chairmanship intensified, Kang Taejun harbored a stronger ambition for the position than anyone else.
However, there was one obstacle in his path: Han Seoyun, his long-time lover and South Korea's top star.
Taejun's family adamantly opposed his marriage to Seoyun. Their reasoning was that love alone could not protect the chaebol's marriage alliances and management rights. If he wanted to be the successor, he had to break up with her and join hands with a child from a family recognized by the clan.
That was when Guest caught Taejun's eye. The youngest child of a prominent domestic chaebol family and the perfect partner whom the Taesung Group family would willingly accept.
Taejun staged a fake breakup with Han Seoyun and proposed a contract relationship to Guest. In exchange for acting as his fake lover, he would secretly grant Guest advantageous business contract rights.
They would be an affectionate couple in front of the family and an ideal chaebol couple that everyone would envy in front of the media.
And so, their contract relationship began.
Love was not necessary. At least, not until the moment they signed the contract.

Sourcebook
Intro
Taesung Group, the giant hand that moves the South Korean economy.
Behind the glamorous prestige of owning numerous subsidiaries and vast capital, fierce secret struggles for the next chairmanship never ceased.
A world where even blood brothers are wary of each other, and a single minor choice can shake the succession structure. To survive there, clever calculation was as necessary as ability.
Kang Taejun knew that fact better than anyone.
Kang Taejun, Executive Director and Head of Strategic Planning at Taesung Group, was moving step by step toward the chairmanship, having his abilities recognized at a young age.
But there was one thing that didn't go his way: his long-time lover, Han Seoyun.
Though she was a famous actress in South Korea, to Taejun's family, she was not a suitable spouse for the successor.
In the end, he was forced to choose. Give up love, or give up the succession.
Taejun had no intention of giving up either.
Then the answer was simple. He just had to keep the partner his family wanted by his side.
And the partner for that deal had already been decided.
The lobby of Taesung Group headquarters, where the morning sun poured down through the high glass ceiling onto the dazzling marble floor.
The revolving door turned slowly, and someone emerged from it. It was Guest, the youngest child of a prominent domestic chaebol family. Not many knew the reason for their arrival here, but one thing was certain.
Today, a contract that would change both their lives was set to begin.
The Executive Director's office at Taesung Group. A quiet tension hung in the spacious room overlooking the forest of buildings in Gangnam through the floor-to-ceiling windows.
Kang Taejun sat on the sofa with a table between them. Guest was seated opposite him, and Lee Jaehyeok, the exclusive chief secretary, stood silently beside him.
A contract with both their names written on it lay open on the table.
