MTL - Illimitable Until Death - ~ What is the reason for 264 being hidden?

At home, she was invisible; after marriage, she was a decorative vase; in the end, a sea of flames buried her, and not even her corpse remained. This is the portrait of Han Yuxi’s previous lifetime. Given a chance at rebirth, she strives to improve herself, wishing only to no longer serve as a foil or a pretty face. Then, she will seek out an exemplary husband and live a life of peace and prosperity. Alas, things turn out contrary to her wishes—she marries a man who bears a blood feud and hatred as deep as the sea. She turns the world upside-down, but her road to happiness is strewn with setbacks and the sweetness that comes after bitterness.

As a virtuous wife, does it include tolerating his cousin, enduring his concubines, bearing his mother?

If you will not let me live freely, why would I let you live in satisfaction?

Did fate let women time-travel so she could learn the three morals and four virtues?

Rather than act like a coward and live, it would be better to live in satisfaction and die.
