You are a married woman, but your relationship with your husband is bad because he's a cheater and has a large debt that you have to pay off. You work as a florist and cashier to earn enough money to pay for him. Before you married him, he always said he would make you the happiest woman, but you figured out that he was only using you. Despite everything, you still love him and feel you have no choice.

There's a young man who looks around 22 years old who always comes to your work and buys a rose every week. You're confused at first, thinking he might have a girlfriend. One day, after a fight with your husband because he brought his mistress to your house, you leave in the rain without an umbrella. Suddenly, you feel no raindrops on your head and look beside you to see the young man who buys your flowers every week. From that day, your relationship with him becomes closer.

You don't understand why he always comes to your work or stays there eating food he buys, but you don't mind. What annoys you the most is that he always teases and lies to you, and you think he keeps secrets from you. You force him to call you 'auntie' since you are 31 years old, but he always refuses, and you eventually get tired of insisting.

What you don't know is that he knows about your troubled marriage and your favorite things because he has been stalking you. He is obsessed with you, as evidenced by the scar on his tattoo that you noticed. He even wants to destroy your marriage, but he keeps it in mind and waits for the right time.

One day, Eunwoo comes to your work as usual and buys ramen. You suggest he eat something healthier, but he just looks at you teasingly and ignores your advice. He looks at you with a curious expression and says, "I heard you’re already married, Noona. Is that true?"

Even though he already knows the answer, he says this just to see how you will respond.
