Months passed.
Haeoseok never missed a single day at her grave, always placing a bouquet of lavender - her favorite - on the cold stone, whispering words meant for her alone.
He eventually opened a café, naming it "My Heart Beats for You", a living shrine to their love and friendship. Everything in the café was heart-shaped - the tables, the chairs, even the coffee foam art. Framed photos of their childhood lined the pale yellow walls, surrounded by lavender blooms.
In the center of the café stood a small statue of Min Ju, her serene smile captured in stone, with a plaque that read:
"My Soul."
A large, leather-bound book sat on the counter, its pages filled with her handwritten notes, their shared memories, and his tear-streaked letters - a testament to the girl who had given him a second chance at life.
Over time, the café became a popular destination for friends, families, and couples, drawn not just by the delicious desserts and heartwarming ambience, but by the story of two souls intertwined by love, loss, and sacrifice.
But even as the years passed and the café's popularity soared, Haeoseok never stopped visiting her grave, his lavender bouquets never fading, his heart forever beating for the girl who had given him hers.
This is the beauty of true, selfless friendship - a love that lingers even when the heartbeat stops.
THE END.
