Because of family reasons, I have to go to the world of tutors to find my memories and the causes of death of the family elders. Every time I recover a little memory, my heart hurts. The more memories I recover, the more pain I feel. Is it because of my power that the world of tutors has a negative impact on me? Or is it the memory of my previous life that affects me in this life, or is there any pain left by me in my previous life that I want me to solve? These things will be revealed step by step, and since the person I love now is the same person as my lover in my previous life, just when my lover and I are walking towards happiness, I never expected that a mysterious person would say that he has a crush on me, and he is someone related to my previous life. Am I with my lover? Or with the mysterious man? Or maybe the three of us are together? Who is it? Who will I be with?
