Tokyo: Eighteen, the System Said I Was Stabbed to Death by My Beloved Daughter

Studying abroad in Tokyo, I woke up with a counterattack system in front of me. "That year, you were twenty-eight, your marriage failed and you were heavily in debt. On the night of your divorce, while you were half asleep and half awake, you hugged someone. It was fragrant and warm, but something was wrong." [So, you were stabbed to death] [Go back to a year ago, find the murderer who stabbed you, and stop everything from happening. Target Person Eighteen-year-old Qianshi Yu looked at the panel and then at his student ID card. I went back to a year ago. Did I make a mistake and go back ten years too early? Also, will I be stabbed to death by a girl in the future? Then this one is divorced. Is it my fault? So heavy! If it was his ex-wife who stabbed him to death. Then you and I are divorced, why do you stab me? If not, you and I are not married, why are you stabbing me? But, who is this person who stabbed him to death, and who is the person lying on both sides of him, taking advantage of the situation?
