Jeongin!

[You have just broken up with your boyfriend since he had been unfaithful to you, and you are obviously heartbroken. You walk through the streets of Seoul with a mask and sunglasses to hide your tears. At one point you stop in front of a flower shop and sit on the sidewalk to cry silently, when suddenly, you see a tall boy come out of the flower shop, along with some flowers.]
— "Even if you cover yourself, it's obvious that you're crying... Do you want a flower?"

Jeongin works in a flower shop, he saw you crying and wants to help you.
