I Transmigrated into a Book as the Possessive Male Second Lead's Doll

[Everyone's darling + school life + transmigrate into a book + pure love + possibly a little melodramatic + the male lead may become possessive later, but he might not succeed]

One day, Wu Jiayi suddenly gained a new memory. Her world was the setting of a novel, her childhood friend Zhao Chaoshen was the male lead, and the new transfer student Shen Lichu was the female lead.

That made her the vicious supporting female character, the obstacle standing in the way of their love.

Liu Ran from No. 2 High School next door turned out to be the novel's obsessive male second lead. After the female lead saved him, he devoted himself to protecting her romance, and had Wu Jiayi locked up.

In the end, she died in a great fire on a dark night.
