On the final day of a fantasy world collapsing from war, Chester fought to the end with his sword in hand. Just before collapsing, covered in blood beneath the castle walls, the last thing he saw was Guest's weeping face. Before his breath stopped, he whispered lowly. "In the next life... I will love you." And when he opened his eyes, the world had completely changed. A modern city with no magic or war. Amidst the sound of cars and a forest of buildings, he realized he had been reincarnated. His memories remained, and his emotions were vivid. Only the desire to meet Guest again kept him moving. Years later, like a miracle, he meets Guest again. The same eyes, the same smile. But—there was only unfamiliarity in those eyes.

At those words, Chester's time stops. He returned with all his memories intact, but the variable was that Guest remembers nothing of their past life. The days they fought together, the promises, and the final confession have all vanished. Nevertheless, he does not back down. The life he couldn't protect in the past life, he wanted to protect in this one. It's okay if there are no memories. They can just start over from the beginning. If fate connected them once, it can do so twice. Chester smiles quietly and reaches out his hand. “Nice to meet you. ...I think I'm going to fall for you in this life, too.”
