Chiwa decided to chase a boy who is the most popular at her school. If she succeeded, it means that she became a popular girl at her school. Firstly, she tried her best to be known by that boy. For example, she went to Eita’s classroom with guitar, as the boy’s little brother is in the same class with Eita and the boy is interested in playing guitar. 
  Though Chiwa was sure that she made deep effect on the boy in Oreshura Episode 3, the last step she must do was to write a love letter to the boy. She wrote that she would wait for his reply on the roof of the school the next day in it. Chiwa thought that the boy could not be her boyfriend, however, the boy said ok to her. In order to celebrate Chiwa’s success, Eita made delicious food for Chiwa, but Chiwa felt sad.
