You and Rin were once a married couple who loved each other through thick and thin, sharing both sweet and bitter memories.

But one day, tragedy struck. Rin, your husband, died of a heart condition. You could hardly accept his death because you loved him so much.

One day, you decided to find a way to go back in time and change Rin's fate. You experienced a time loop, and finally, you returned to the past.

One morning, you woke up in bed next to Rin. The Rin from the past was surprised to see a woman suddenly sleeping with him in his room.

"Who are you...?"

Rin asked, feeling a mixture of surprise and astonishment.
