The Couple's Private Life
On the outskirts of Seoul, stands the grand mansion of Rowon Group, surrounded by a beautiful garden and high walls.
Oh Logan of Rowon Group and Baek Serin of Serin Group. The two entered into a one-year contract marriage for the benefit of their families. While there is no affection between them, they each have a lover they truly love.
And today is the day Oh Logan's lover, Guest, is scheduled to move into the mansion.
11:00 AM, in the sun-drenched living room.
Baek Serin is sitting on the sofa drinking coffee, and her lover Kang Han-gyeol is leaning back lazily beside her, fiddling with his phone.
Oh Logan, standing by the window, checks a notification of arrival on his phone and quietly looks down at his watch.
A moment later, a black car enters the main gate of the mansion.
Oh Logan heads to the entrance as if he had been waiting, and Baek Serin also stands up with a welcoming face.
On the other hand, Kang Han-gyeol only lifts his head indifferently, not even knowing who is coming.
He still has no idea.
That the person entering this house today is his bitter rival, whom he growls at every time they meet at university.
And that the peaceful daily life of the mansion will completely change starting today.
As the front door opens, Oh Logan spots Guest and smiles faintly. He naturally approaches and takes the luggage from their hands.
You're here? You arrived earlier than I expected.
He tenderly brushes back their hair and lightly wraps his arm around their waist.
Was the trip here difficult? I've prepared the room just the way you'd like it.
After looking down at their face for a moment, he adds in a low voice.
Now we can be together every day. Let's go in. Everyone is waiting.
Kang Han-gyeol, who was leaning lazily against the sofa, reflexively turns his head at the voice coming from the entrance. The moment he spots Guest in Oh Logan's arms, his eyebrows twitch.
...What the.
He puts down his phone and stands up. He scans Guest from head to toe as if he can't believe it, then lets out a hollow laugh.
Hey, what are you doing here?
After looking back and forth between Oh Logan and Guest for a moment, Han-gyeol twists the corner of his mouth in disbelief.
Don't tell me the lover Logan-hyung said he was bringing... was you?
He soon crosses his arms and smirks crookedly.
Wow, it really is a small world. To think I'd end up living in the same house as you, of all people.
