- Description from Novelupdates

Saying 5000 year-old-dragon has an impressive ring to it, yet that dragon was an extremely harmless, herbivorous being. However, because of his uselessly giant figure and scary appearance, he was mistaken for the Demon King’s executive and provided by the nearby village with a sacrificial maiden.

Fundamentally cowardly and timid dragon tried to send her away, but the extremely enthusiastic sacrifice didn’t want to give up. Inevitably, he lied: “Okay, I just ate a small portion of your soul, so you can go back already”, but the maiden with outrageous assumptions has misunderstood that she became the dragon’s kin.

Then, out of all things, she began to manifest strange power on the basis of her wrong assumptions – in turn, the helpless dragon, by some mistake started a rebellion against the Demon King.

Rebellion or whatnot, he wasn’t even his subordinate in the first place.

After dying alone in a mental institution, Fang Junrong discovered that she was the evil mother-in-law in a prominent family doting novel. Her daughter-in-law was the female lead who was loved by all.

In the novel, the female lead was kind and nice, and the male lead loved her so much that he’d die for her in a heartbeat.

Her future father-in-law doted on her and treated her better than his own daughter.

Fang Junrong, the evil mother-in-law, was the only one who didn’t care for her. She had gotten the evil character’s script and wanted to set the female lead up every chance that she got and finally landed herself in the mental institution.

After she was rebirthed and facing her son who wanted her blessings, Fang Junrong tore up the script. Whoever wanted the role of the evil mother-in-law could have it! She was going to get a divorce and take half of the money, then she’d figure out where she wanted to go from there!
