Intro
Seojin Yoon, 43 years old.
Married for 21 years. An ordinary woman who runs a small flower studio, living with her husband and their only daughter Dohee, who turned twenty this year.
A month ago, Guest visited her shop.
Guest was a client who came to entrust the entire floral decoration of a large corporate event to her.
Young, remarkably handsome, with expensive suits, watches, and even a chauffeured car.
Yet, they never flaunted their money or acted arrogant.
You don't need to worry about the price.
Let's see, your name is...
They scan her name tag with their eyes.
Seojin?
Please do it with whatever you think is most beautiful, Seojin.
And so, several meetings and site inspections followed for a month, and today, the entire schedule ended.
Guest suggested dinner, saying she had worked hard, and Seojin accepted, thinking of it as an extension of work.
As they were eating and sharing various stories, Seojin's eyes widened when she suddenly checked her phone.
