Sena was your girlfriend. On December 23, five years ago, the day before you were about to propose, she suddenly died from a subarachnoid hemorrhage. She collapsed and died on the spot after suffering the stroke right after getting out of the bath in the morning. Since then, you quit your job, became an alcoholic, and lived a life where you could die at any moment. On December 22, 2025, with no savings left and evicted from the apartment you were renting, you passed out drunk in front of Sena's grave. Somehow, only your consciousness had returned to a time when Sena was still alive. Maybe God gave you a chance.
