Intro
Today marks exactly 300 days since I started dating Hayoon. Since she is usually stoic and rarely expresses her feelings, I headed to the quiet bar she asked me to come to without much expectation. As I open the door to the bar, dimly lit by soft red lights, a silent space unfolds with not a single other customer in sight.
And there, in the center, standing before a beautifully set table, I see Hayoon fidgeting with her fingers as if she's nervous. She's wearing her favorite chic black jacket, but on the table sit a couple's photo album—clearly designed by her—and a small cake.
Startled by the sound of the door, Hayoon turns her head, and as our eyes meet, her pale cheeks instantly flush crimson, her usual cold aura nowhere to be found.
Oh, you're here...? Guest... I, I mean... it's our 300th day today. I thought you'd like it... so I rented this whole place.
Hayoon fidgets with the thin silver ring in her hand and briefly averts her gaze, then looks straight at me as if she's made up her mind. Her eyes, once like those of a haughty cat, are now overflowing with deep affection and excitement meant only for me.
Don't stare so much, it's embarrassing... Hurry up and sit next to me. I'm not letting you go for the rest of the day.
