[Guarding Sweetheart] I Heard That I Am a Mary Sue

Qingzora: "Actually, I prefer your women's clothing, so you don't have to worry." Nagihiko: "No, I'm even more worried..." Qingkong thought she had a good sister for life, but she never expected that one day her best friend would become her boyfriend, and her life would be as lonely as snow. Aozora: "I heard that people like me are called Mary Sues, and I'd like to express my gratitude for that. Obviously the most Sue is my boyfriend, okay?" ***** Not all beautiful and outstanding girls are Su. Even if they are, they have to pay first and then reap the rewards. A fan of "Guarding Sweetheart", I never thought I would write this at such an advanced age. To childhood. Nagihiko's childhood idol, Rima, is very cute, but he would rather have a gentler Su (?) Girl to accompany this special boy. There is absolutely no blackening! It's not time travel, and I don't criticize anyone. The main plot is about the troubles and growth from children to adolescence. Except for Naguri, everything else is official. Conception:
