Helan Shiyu accidentally traveled to her previous life after jumping into the sea. In this world, she obtained a system numbered 0620, which issued a task asking her to change the miserable ending of her previous life.
Later, she fell in love with Shen Bieshu, the prince of the enemy country, and was murdered on her wedding night. Later, she met Shen Bieshu on the battlefield, and finally died on the battlefield. The moment before she was wiped out, the memory of her previous life appeared in her mind, and she found that everything she had experienced had already been experienced once in her previous life. Finally, the system asked her if she regretted it, and she only said one sentence, "If you fall in love with him, it doesn't matter even if you make the same mistakes again."
Concept: run through with tragedy
