After Returning to Modern Times, His Highness the Crown Prince Regretted Going Crazy

After time travel, I accidentally had a romantic relationship with the prince. I don't want to climb a high branch and sneak away quietly at night. The prince searched for me with great fanfare for five years, and I hid him with his children for five years. It wasn't until the eve of the prince's wedding that I found a way to go back. Looking at my ignorant son, I had to send him back to the East Palace. "My dear, take this jade pendant and your father will recognize you. If he asks about mother, you will tell me that I have died long ago."
