Tsukamoto Tenma is a second grader in high school who, like other girls her age, falls in love. However, she could not bring herself to confess her love to her classmate Karasumaru. She discovers that Karasumaru will transfer out next year and, with the help of her friends and her little sister Yakumo, tries to confess her love. Tenma also uses unorthodox methods such as disguising herself as a nurse or shooting arrows with a love letter attached to express her feelings for him. On the other hand, Harima Kenji, a delinquent, has feelings for Tenma. Unfortunately, Tenma's preoccupation with Karasumara ensures that she doesn't notice Harima's affection, much to Harima's dismay. To make matters worse, one day, he sees Tenma and Karasumaru having lunch together. This causes him to skip school and embark on a journey of enlightenment.
NOTE: There were two 190 published and which was a mistake. The publishers corrected this mistake just after 231 and so they published 233 after that. So there was no chapter 232.
