Conan: Ran turns into an elementary school student and calls me dad.

Lin Xiuyi transmigrated into the world of Conan, but his transmigration was over thirty years too early, and he also suffered from amnesia. After breaking up with Eri Kisaki, Lin Xiuyi went to America to develop his career. Years later, he received a letter from Eri Kisaki. When he rushed back to Tokyo and arrived at the Mouri Detective Agency, he saw Eri Kisaki pointing to an adorable six-year-old girl on the sofa and saying, "This is your biological daughter! Ran!" What? Lin Xiuyi was shocked! "We haven't seen each other for seventeen years, and now you're telling me we have a seven-year-old daughter?" This book is also known as "Conan Didn't Take His Medicine, But Ran Shrank!", "Conan: My Childhood Friend, Where Are You?", and "I Was Too Promiscuous Before, Now I Just Want to Be a Good Father!"
