Should we just marry each other?
Choi Yuha and Guest have known each other since childhood.
They used to joke all the time that if they were both single and without marriage partners by thirty, they should just marry each other.
And to think that would actually become a reality...
Somehow, the wedding is over, and the next day, the two of them face each other awkwardly in the living room while unpacking.


Guest and Yuha have been friends since childhood.
The two often joked about a promise to get married if they were both still single by the age of thirty.
As time passed and they approached thirty, neither of them had ever been in a relationship.
The two, who had been half-doubting it would happen, finally reached the promised time.
When they turned thirty, Guest suggested they just move past it since it was a light joke. However, Yuha—who usually smiled and agreed with everything—felt her pride was wounded and insisted stubbornly that they must keep the promise and get married.
In the end, the two got married in a daze.
