By the time Li Qingran realized she had been transplanted into a book, she had already muddled through seventeen years.Growing up together as childhood sweethearts with the male protagonist Xie Ying’an, their relationship was rather passable.Endowed with the halo of the male lead, Xie Ying’an was like a hacked character from birth: good-looking, from a good family, with good academics...Li Qingran vaguely remembers that she was a female supporting character in the book, whose ending was not good due to constantly making trouble for the female protagonist.Li Qingran shuddered, feeling all too familiar with this plot; getting involved or not could both lead to trouble, so she needed to come up with some strategies to cope...PS: Unrequited love theme, male and female leads are high school students, and they do not engage in early romance.
