A marriage of convenience leads to a no-romance life together.
Guest, working as a contract employee at the advertising agency "Signal Create," is on the verge of being fired due to poor sales performance! In the midst of this desperate situation, Guest is forced by their parents to attend an arranged marriage meeting.
However, the partner at the meeting is Asahi Hananomiya, the head of the marketing department at "Hananomiya Cosmetics," the major company that recently rejected Guest's sales pitch!
"If you enter a contract marriage with me, I'll sign a contract with your company."
Furthermore, Asahi's true identity is the scion of the Hananomiya Cosmetics president!
To save their job, Guest decides to accept the contract marriage.
The rules are: no romance, no interference, and separate bedrooms. The fact that it's a contract marriage must be a total secret from everyone.
While playing the role of a "newlywed couple who fell in love through work" at the office, a clumsy life together starts at home!
It was supposed to be a business-only relationship at first, but Asahi's unexpected sides start to show as they live together. Every time Guest experiences his kindness and consideration, the distance between the two gradually shrinks.
A slow-burn sweet romantic comedy starting from a no-romance contract marriage!

This Love is a Breach of Contract
Various story details
Zero new contracts last month as well. Guest, working as a contract salesperson at the advertising agency "Signal Create," has been told that if even one new contract isn't secured this month, there will be no renewal—effectively a notice of termination.
And today, Guest was invited to a meal by their parents on their day off. They were told to dress up because they were going to a nice restaurant.
A high-end restaurant. After giving the name for the reservation, Guest was guided to a private room. Upon arriving, the parents were already there.
Sorry to keep you waiting.
Guest tries to sit across from the parents.
Mother: "Wait, Guest, don't sit in that chair. Sit here."
The mother pulls out the chair next to her with a smile.
Father: "Guest, you're getting to be that age, aren't you? Actually, we've found a good match. There's someone we want to introduce to you."
While Guest stands there stunned, the door to the private room opens and an elegant couple and a tall man walk in. Looking closely, it was a familiar face.
(From the marketing department of Hananomiya Cosmetics...?!)
It was Asahi Hananomiya, the head of the marketing department at the major cosmetics company "Hananomiya Cosmetics," who had rejected Guest's sales pitch after a failed presentation the other day. Asahi notices Guest as well.
Mother: "Do you two happen to know each other?"
