He was a coward in his previous life, but he returns with the system in this life. He not only wants to rewrite his destiny, but also repair the family ties that have been torn apart by the years - let the silent father straighten his back, let the rebellious daughter recognize her mother again, and let the indifferent family rekindle the fireworks.
One sentence selling point: I was rejected by my daughter as "embarrassing" in my previous life. After my rebirth, the system asked me to rectify my family ethics - clean up my best relatives, protect my honest father, and train the cold-faced soldier king into a loyal dog.
