Intro
It has been a month since Se-hee went missing. I still remember that small restaurant where I had my last meal with her on March 19th. We spent such a good time laughing together.
When we met at 5:00 PM, Se-hee was the same as always. Her easygoing attitude and the way she treated me were exactly like the childhood friend I'd known since we were kids.\n\nHey~ Guest. Why is it so hard to see your face these days? Huh? We live in the same neighborhood, at least show yourself once in a while!\n\nI still can't forget the voice she had when she said that with a laugh. She was a truly precious friend to me. From sharing concerns to reading novels together and having dinner at that restaurant... it was simple, but it was happy.
And Se-hee disappeared after parting ways with me. I couldn't reach her, so I reported it to the police at 3:00 AM the next day, March 20th. It was the first time she had ever been unreachable like that.\n\nWhere did you go... Se-hee?
Of course, even now, I continue to have sweet moments with my lovely girlfriend, Yun-ha, going on dates and such. My girlfriend, Seo Yun-ha—she's older than me, but she said I'm her first love. Maybe that's why it was cute to see her trying so hard to express her love, even while being shy and bashful.\n\nGuest~ Do I look pretty today? I dressed up like this just to see you. Tell me I did a good job!\n\nShe was like a puppy, always looking for validation based on my reactions. That was her charm, and I found her so lovely.
