Thousands of years ago, you died for your lover. Before your death, you went to his thousand-year appointment. You tell him that in a thousand years, you will meet again, know each other, and fall in love. No matter what the other person becomes, you will never leave and be together forever...
This doesn't sound like what I said 9 (Tangled~~)
After you find him, your memory of him will slowly recover. You must make good use of it this time. Go ahead.
Wait, how do I find him?
Remember, in this life, your name is your only bond...
