IUC "Black Shadow" researcher Chen Chen came home from get off work one day, and the unknown little loli squatted at the door and begged for adoption, clamoring to eat the pots and pans at home. After that, Chen Chen lived a daily life as an "aunt". "Auntie, auntie, is this how it's used?" Chen Momo pressed his fragrant grandma into the bottom of the box. "Auntie, please give me a name!" Chen Chen glanced at her with squinted eyes and replied: "I'll call you Xiaoguo. Don't you like pots?" "Auntie, auntie..." Chen Chen had a headache, "Don't call me aunt! I don't look that old!" (Crash) "..." Until "they" came to the door, Xiaoguo played with a yo-yo with a black shadow in his hand. As strange things happened, Chen Shen keenly realized that Xiaoguo's relationship with him was definitely not simple. At the same time, the research materials in his hands also showed that he had fallen into a puzzle. Strictly speaking, little lolita have existed for tens of thousands of years and are not underage. HE, double clean. Chen Xiaoguo, a scheming little lolita, × Chen Chen, a cold and serious researcher If there are any contradictions in the plot, please correct me.
