After the Female Supporting Character Mistook the Villain for the Male Lead

[A feisty little white flower x a smiling, great demon lord villain] Updates according to the rankings before signing; 3,000 words daily after signing (wishful thinking) Hua Shuangying transmigrates into an old-school tragic romance novel as its vicious supporting female character. According to the plot, the male lead saves her, and she falls for him at first sight. From then on, she stirs up trouble between the leads, gets face-slapped over and over, and finally, driven by love and hatred, secretly sides with the villain. The male lead runs her through with his sword to prove his Dao. Little Hua: Seriously? To stay alive, Little Hua has no choice but to work diligently to survive the plot against all odds. Luckily, the male lead seems unusually easygoing. In the morning, a young man from a prestigious family humiliates Little Hua, saying she tried to paint a tiger but ended up with a dog. By afternoon, Little Hua uses the sword the male lead gave her to beat him until he begs for mercy. That day, the young lord of the demon realm mistakes Little Hua for someone else and takes her back to his cave. The next day, Little Hua uses the male lead's secret sword technique to beat the young lord back into his original form, where he clings to her leg and begs for mercy. One day, the Sword Lord forcibly takes Little Hua home to be his cultivation partner. An hourglass later, the male lead shows up in person and snaps the Sword Lord's bonded sword in two. Later, to complete her task, Little Hua decides to clear things up with the male lead and go secretly ally herself with the villain. She raises an eyebrow at the male lead, who's confessing to her, and says, "This was just a game for both of us. You didn't really take it seriously, did you?" As soon as the words leave her mouth, Little Hua sees the villain's favorability, which she'd never paid attention to before, bouncing between 100% and -150%. A cold sweat breaks out all over her. She packs her bags and runs away in the middle of the night, then sheepishly comes back the next day. She clutches the hem of the fake male lead's robe, who's actually the villain, and awkwardly begs him to take her back. The great villain smiles warmly. "Sure." Little Hua sees his favorability fluctuate even more wildly and starts shaking even harder. #It's hard to explain, because I'm just an innocent little flower# 1. One-on-one romance. 2. The heroine is a true ordinary citizen, a passionate, growth-oriented protagonist. 3. A bit of a slow burn. Theme: Those who help themselves will be helped by heaven.
