Help! The System Is Making This Socially Anxious Introvert Become Everyone's Crush

Fang Ruyue transmigrated into a book and became a nameless cannon-fodder character. All she wanted was to laze around in the back courtyard of the Marquis's residence. Her convenient husband returned with "amnesia," bringing along Su Yuqing, the woman who had saved his life. Her mother-in-law put the question to her: "Ruyue, should we let this orphan girl stay?" Fang Ruyue, struck by social anxiety: "E-either way is fine..." System: [Host detected refusing to socialize! Punishment: Charm +10!] Fang Ruyue: ??? Help! Don't pay attention to me! Her convenient husband felt guilty and wanted to consummate their marriage. Thinking fast, Fang Ruyue said, "My lord... I... am not feeling well..." System: [Consummation mission failed! Punishment: Beauty +10!] Fang Ruyue: ...Just destroy the world already! You want this blessing instead?! Her sister-in-law provoked her, and all Fang Ruyue wanted was to run away. But her mother-in-law misunderstood: "Good girl, you've suffered so much! I'll give you control of the household. Deal with those wicked servants however you like!" Forced to play along, Fang Ruyue took charge of the accounts and put people in their place... Before long, she had become everyone's darling in the capital. In the end, even her mother-in-law, the empress, dragged her back to make her empress? Fang Ruyue looked at the dragon throne, close to tears. What happened to my cannon-fodder script? How did this socially anxious, lazy girl end up ruling the empire?!
