Fated by Wood and Stone in Swords of Legends

Luo Xuanji had four regrets in her life: her parents died young, leaving her alone; the man she entrusted her beloved younger sister to was no good. Her dearest friend left her with a lifelong regret, and her marriage to a man as unyielding as stone came to nothing. One day, she opened her eyes and found herself in another world. She thought Heaven had given her a chance to reclaim everything she had lost, but only later did she realize this was another ill-fated union between stone and wood. →_→ This story is a companion piece to How Did Prince Changqin Turn Evil?
