Who Gets It? I Transmigrated into a Book and the Demon Lord Forced Me to Love Him!

[Two Male Leads! Sweet Romance, Adorable Child, Devoted Love, Yandere, Scheming, A Couple with Eight Hundred Plots Between Them, Food, Daily Life]

Ji Tang, male, twenty-four years old, transmigrates into a book, into "The Domineering Demon Lord Falls in Love with Me," where he encounters a thoroughly unreliable System with outrageously expensive prices.

He thought all he had to do was follow the main quest and bring the male and female leads together. But the System slacks off halfway through, and the male lead was playing dumb all along!

Hah! Then let the Demon Lord find out he's forced a real ancestor to come home!
