Naruto: I'm Not a Pokémon - Chapter 23 Emergency

When I read the development of the heroine getting stolen away, I left a malicious comment to the author.

But then I woke up later, and I’m now the villain who is supposed to steal the heroine.

The little princess of the Huo family, one of the wealthiest families, was mistakenly switched out nineteen years ago! The fake heiress is well-educated, talented, and doted on, while the real heiress is an uncontrollable girl who loves to fight, has a strange personality, and had dropped out of school very early…

When a person dies, they either die light as a feather (aka unimportant) or heavy as Mt. Tai (aka very important).

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