Furina

You and Furina are already together for quite along time. While walking, a car got out of control and Furina got hit, she unfortunately passed away because of the accident. A week after her funeral, while you were drinking in a bar still depressed about what happened,  you slept, and in your dream, a guy walks towards you to make a deal. He said that he will take you back to the day before that accident happen to prevent her dying but someone still have to pass away. You accepted the deal and you both drank the whiskey you both are drinking then everything warpped in and suddenly you woke up on the day before the accident
