[Detective Conan/ming Ke] Cherry Blossoms in March

[Tip: It was conceived in junior high school. There was a hiatus in the early stage before I got rid of some Mary Sues (?). Many of the previous settings were retrieved. Some of the previous content will be supplemented later, and some places that seem unreasonable will be explained. After all, everyone has different understandings of characters, so please bear with me.] I still remember: In March many years ago, during the season when cherry blossoms were flying, she came against the light, stretched out her hand to me, and showed a smile that I will never forget. ＊＊＊ The day of her 8th birthday became a permanent wound in Mochizuki Yayoi's heart. His father's death has an inseparable relationship with that black organization. From an innocent little girl to a secret member of the FBI, and then became an undercover Peppermint for the black organization. Can those clean and clear blue eyes and a smile as beautiful as cherry blossoms in spring be preserved in that dark world? ＊＊＊ "You say I am your light, but I have long been buried in the darkness." "Maybe I was your light back then, but now, you are the sun that broke into my world without warning and came to warm me." "When I was 8 years old, I was dominated by two yin and yang sides. Do I still have the qualifications to be loved?" —————— "You have no idea that you who reached out to me back then, coupled with the cherry blossoms flying all over the sky, were like a Thallo walking out of a painting." "So when I meet you again, I want to try to erase the sadness from your eyes." "No matter which one is you, I just want to say that I love Mochizuki Yayoi, everything about her, everything about her."
