The Vicious Supporting Female Character Must Beware of the Mary Sue (Transmigrate Into a Book)

Bo Ying is deeply in love with Liu Muzhi. She doesn't know why, but she is definitely in love with this man. Bo Xing, her half-sister and a delicate white-lotus beauty, also loves Liu Muzhi, but Bo Ying doesn't care. What she does care about is Liu Mengzhi, Liu Muzhi's incredibly annoying younger sister. Bo Ying feels as if the two of them must have had a blood feud for eight lifetimes. Liu Mengzhi: heaven's favorite, an over-the-top Mary Sue, a great wingwoman for Bo Xing, and a stumbling block for Bo Ying. When Liu Mengzhi once again arranges for Bo Xing and Liu Muzhi to spend time alone together, Bo Ying finally loses her patience. "Liu Mengzhi, do you hate the idea of having me as your sister-in-law that much?!" Liu Mengzhi gives her trademark fake smile. "I do hate it. Why don't you be my girlfriend instead?" * Liu Mengzhi transmigrated into a book, complete with a System. Her mission is to help every male and female protagonist couple find their way to each other. The mission is easy, and the process is boring, so this time she decides to find herself some fun within the limits of the rules. The System says Bo Ying is absolutely straight, a vicious supporting female character created according to the fundamental premise that she loves the male lead, so Liu Mengzhi could never turn her gay. AI really is so ignorant. What she wants to do isn't something shallow like "turning her gay." She wants to help female characters like Bo Ying, who were hastily written, become truly vivid and real people! System: Don't bother making excuses. Just remember the bottom line: you absolutely must not get involved with anyone in the world of the book, or you won't be able to leave. Liu Mengzhi: Understood. * Bo Ying thinks she must have misunderstood what Liu Mengzhi meant by "girlfriend." She means a romantic girlfriend, not just a female friend, right? Then why doesn't Liu Mengzhi kiss her? * June 4: Going VIP. Three chapters will be released that day. Coming soon: [Sick] Pei Yanning is a quiet, introverted, thoroughly ordinary first-year university student. Her goal is to get through university in peace. But for some reason, Xue Songyi, her classmate and roommate, who became famous for her beauty as soon as she started university, seems to have made Pei Yanning her sworn enemy. Pei Yanning doesn't want to fall out with anyone, much less cause a scene, so she meekly tries to make peace. "I don't want to start any trouble. You can tell me what I should do to make you happy." Then she gets an answer she never expected. "...I want you to kiss me." * Pei E: You're imagining things again, my dear little sister. Pei Yanning: Aaaah! It's real! Pei E: Huh? Is she sick or something? Don't be afraid. Let your big sister teach her a lesson for you! Pei Yanning: Wait! Peace and love. * Xue Songyi was sick. It took her three years to finally find the cure. But the other person no longer recognized her, and was completely different from the person in her memories. That can't be right. Her upperclassman wasn't like this. Theme: Be independent and love yourself. Search for life's true meaning while fighting against a predetermined fate.
