The Cp I Arranged, I Dismantled with My Own Hands

She wears a book to become a vicious female supporting character, and the story of the male and female protagonists in the book are brought together and then separated, and she seizes every loophole to complete the task. It is a daily life on campus, heart-stirring, contains multiple pairs of cps, no female competition, all members have 1v1 pure love. Please bear with me as this is my first time writing a book.
