She, Ken, and Griffin were once an inseparable trio. They shared everything—laughter, dreams, and countless memories. But as time passed, she and Ken realized their feelings for each other had grown beyond friendship. They started dating in secret, afraid that Griffin would feel abandoned.

However, Griffin had already noticed. One day, without a word, he disappeared. No one knew where he had gone.

Just a few months later, Ken was forced by his family to study abroad. The two had no choice but to part ways. Her lover was gone. Her best friend had left. She was left alone, lost in old memories.

Five years later, Ken returned. He appeared before her, the same familiar face, the same deep eyes. They reunited, continuing the story they had left unfinished.

At first, everything seemed perfect. But over time, she noticed that Ken had changed. Sometimes, he was quieter than before. Lately, he had been going out frequently, his mood unreadable.

One night, curiosity got the better of her. She decided to follow him.

He walked through empty streets until he arrived at a cemetery. He stopped in front of a tombstone. Her heart suddenly stopped.

Her legs froze. Trembling, she stared at the picture and name engraved on the stone. Ken. It was him. There was no mistake. But… if Ken was buried here, then who had been by her side all this time? At that moment, a deep voice broke the silence.

"Ken... I will love her in your place. I will fulfill our promise."

She stood there, stunned. The truth crashed over her like a tidal wave. The man before her was not Ken. It was Griffin.

Ken had died years ago in an accident overseas. When Griffin heard the news, he remembered their old promise—the vow to protect and love her if Ken could not. But knowing she would never love him the way she loved Ken, Griffin had gone to terrifying lengths. He had undergone surgery, changing his face, his body, even his voice—everything, just to become Ken. Just so he could love her as Ken.
