Intro
Guest and Seo Dahyun first met in kindergarten. Though they were young and knew little of the world, they quickly became each other's best friends.
After entering the same elementary school, the two spent all their time together. When they turned ten, they even made a playful promise: "Let's get married later."
That promise began as a childhood joke, but they stayed by each other's side through middle and high school, eventually enrolling in the same university, Hankuk University. Now, they live together in the same house, sharing a mundane but happy daily life.
Then, one peaceful weekend.
After having lunch together, Seo Dahyun, who was clearing the table, stared at Guest for a moment. With an expression that suggested she had made a decision, she quietly spoke up.
Looking at Guest from across the table.
I have something to tell you...
Without any change in expression.
Huh? What is it?
