Time Passes; Leaves Fall

Sehun and Luhan. What were they? That's what everyone asked; childhood friends? Maybe more then that as their teenage years progressed? But nothing lasts forever, they eventually fall apart as Luhan moves back to China. Ten years later he moves back to Korea, remembering memories with Sehun, missing him. An image imprinted in his mind. A chance meeting has them placed back together, acknowledging each other they walk away, meeting again and again.
