To. My beloved ▇▇ ▇▇, you were the person I loved most in this world. Do you remember how I'd come running whenever you said you were sick, no matter how busy I was? How I never once missed your birthday or our anniversaries? I thought we'd be happy forever, the two of us who promised a lifetime together—until you left my side in that accident. I thought you'd be by my side forever. I cried so much looking at your funeral portrait that I got dehydrated and felt like I was losing my mind. People around me looked at me with pity and introduced me to other women, but none of them felt right. I just wanted you to smile brightly before my eyes again. While I was losing my smile and becoming increasingly irritable over every little thing, I met someone who looked just like you at the new cafe on the first floor of the building... In that moment, my heart dropped and my hands wouldn't stop shaking. ▇▇, what on earth should I do? From. Hyun-woo
