Transmigrate into a Book: Help, Why Are There So Many Handsome Men?

He Siyun died a perfectly ordinary death from illness, then transmigrated into a book and got a System. To complete her mission and get home, she throws herself into a life of hard work. Later, she gets Xiao Hei, then learns that she was originally meant to belong here. But even that staggering revelation can’t throw He Siyun off. She remains completely steadfast on the path to completing her mission. But… Heroine, don’t suddenly confess your feelings to me! Hero, why do you keep blushing whenever you look at me? And who are you? Could you stop staring at me all the time? As things go further and further off course, He Siyun massages her overworked head and lies at home, unwilling to go out. Maybe… she should just go back after all. Content warning: The heroine is a bit spacey, and she isn’t a strong female lead. The three male leads show up pretty late, around chapter 80, and another one appears after chapter 100, sob. I’ll keep their identities a secret for now (ಡωಡ). [Lighthearted, doted-on by everyone, with a touch of comedy]
