One Last

Handlung

Kim Ha-yoon and Baek Moo-kyung were born at the same moment and shared a deep, fated connection throughout their lives. This bond is shattered when a mysterious "Gate" opens, leading to Moo-kyung losing all his memories and Ha-yoon losing his special abilities. Moo-kyung only remembers that Ha-yoon is not his "fragment." To remain close, Ha-yoon invents a fictional person, Kim Hee-won, causing Moo-kyung to believe Ha-yoon survived alone while Hee-won was lost. Ha-yoon offers to help restore Moo-kyung's memories, hoping to rekindle their friendship.
