Plot

When Teru's older brother died, she was left with little more than a cell phone containing the text-address of an elusive character named DAISY, who Teru's brother had told her Daisy would watch over her. Daisy would always mention "I'm always watching over you." DAISY became Teru's pillar of strength, over the next few years as he sent her encouraging words through his phone, whether inspiring or mere chatter, as she faces her life alone.

One afternoon, after bullies from the student council are mysteriously driven away, Teru accidentally breaks a school window, which results in her working for the grouchy, cruel school janitor named Tasuku Kurosaki. As Teru begins working for the unlikable school janitor, her feelings begin to surpass that of master and servant and she begins to question DAISY's true identity. Thus begins an unlikely friendship between a 16-year-old high school girl and a sly but smart 24-year-old man. As time goes by the two become close and Teru falls for Kurosaki. What she doesn't know is that he has feeling for her too, but can not return them for a number of reasons, the most important reason is somehow he was the one who caused her brothers death.
