Who Knows? After Passing Through the Book, I Was Forced to Love You by the Demon Lord!

Two male protagonists! Sweet pet, cute baby, single pet, yandere, sinister, couple with 800 evil intentions, food, daily life Ji Tang, male, 24 years old, went through the book "The Overbearing Demon Lord Falls in Love with Me" and encountered a particularly unreliable system and extremely expensive prices. I originally thought that I could just follow the main mission and promote the emotional connection between the male and female protagonists, but the system was ruined halfway through and the male protagonist was pretending to be a pig and eating the tiger! Oh! Then let the Demon Lord know that he forced an ancestor to come back!
