Transmigrate into a Book: The Prince’s Cinderella

Song Yihu transmigrates into a Mary Sue novel and, on her very first day, offends a famous top student in the city by accidentally taking the seat of Lin Xiaoxiao, the Mary Sue heroine. Everyone mocks her for overestimating herself. The gloomy, lovesick male supporting character and campus heartthrob walks up to her and says, "Woman, go apologize to Lin Xiaoxiao this instant!"

Miss Song forces a smile. "It's broad daylight. What are you doing, dreaming? Is my temper too good, or are you just blind to the situation?"

#The story of a rich young lady turned supporting character who takes the world by storm.#

It's Mary Sue, sure, but is it still Mary Sue if it isn't so Mary Sue?
