I Abandoned the Heroine to Serve the Villainess

Lin An'an accidentally discovers she is a cannon fodder supporting character in a romance novel. After slavishly worshipping the heroine Zhou Tian and dying tragically, she is unwilling to accept her fate and vows to change it. On a high-speed train where she meets a vicious supporting character, the latter offers Lin An'an 5000 yuan for a seat. Jealous and resentful, Zhou Tian morally coerces Lin An'an into rejecting the offer. However, the sycophant Lin An'an slaps Zhou Tian and immediately embraces the vicious supporting character's leg.
