Hostess: "Father, you are so good to the slave family, just like... My dead biological father."
Villain (lovingly): "Silly boy, the truth is what you rely on."
Female protagonist (inner OS): Yes, after all, you are the murderer of my whole family. Be good, take another sip of this bowl of "Haodaer" brand ginseng soup. After finishing this bowl, the next bowl will send you on your way.
In order to take revenge, the heroine accepts the enemy who killed her father as her "adopted father". With her pair of innocent eyes and perfect tea skills, she coaxed the villain's family into a circle, first as the group's pet, then as a troublemaker, and finally made them understand one truth: The premise of "a loving father and a filial son" is - you didn't kill my father.
