My Little Monster is a Japanese manga written and illustrated by Robico about the relationship between a girl named Shizuku Mizutani and a boy named Haru Yoshida. It was serialized in Kodansha’s Dessert magazine from August 23, 2008 to June 24, 2013.
My Little Monster focuses on the relationship between Shizuku Mizutani, who has absolutely no interests except in studying and her plans for the future, and a boy named Haru Yoshida, who sits next to Shizuku in class but rarely attends school. After Shizuku is tasked with delivering class printouts to Haru’s home, she meets Haru, who immediately greets her as a friend, starting their new relationship. Nicknamed “dry ice,” Shizuku is renowned as a girl who is emotionless and cold. However, when she met Haru she was touched by his innocence and his lack of knowledge towards human relationships. Though known as a violent and uncontrollable monster, Haru is actually kind and gentle. Haru immediately declares his love towards Shizuku, but it takes much longer for Shizuku to realize and accept her own feelings towards Haru. Together, as two previously unsocial beings, they help each other learn how to care for each other and relate with their friends and family.
