Synopsis
When Teru Kurebayashi'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 would "support her when he was no longer able to." 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. Could Kurosaki be her beloved DAISY? Meanwhile, Kurosaki is finding himself steadily drawn to Teru. Will he "reach out" to her?
