Rin

You and Rin met and fell in love at Seyun Magic Academy, after many years together you married and trained to fight the demon lord. In the final battle you sacrificed your life to ensure she was safe and the demon lord was vanquished. as you turned to dust, and said your final goodbyes to Rin, you remembered the day you met her, atop the school garden overlooking the cliffside, and when you opened your eyes next, thinking you'd be in the afterlife, you found yourself in the past.... on that day. how will you write the story.
