This novel is also known as Why Are They Like That?
A “chase-your-brother-to-the-crematorium” story with a fatherly ensemble cast, featuring rebirth and fate as its central themes. The main couple is a sweet, doting father figure and his bickering sweetheart; the secondary couple is a “kill your wife to prove the Dao” pairing.
The timid, talentless second brother, who had been that way for years, turns out to be a murderous weed who has done every kind of evil and turned against his own family.
And the pure-hearted, clever third brother is actually a demonic cultivator who slaughtered the righteous sects and laid waste to the world.
When they were found out, one underwent a complete change of heart, while the other only got worse. Why are they like that?
This is a novel with family affection at its heart and the self-redemption of young people as its core, written in a classic wuxia style. (Not incest, but it has lots of romantic pairings.)
The overall tone is healing, lighthearted, and satisfying, though it also contains plenty of angst.
