Ep. 6: Yuki estuda com Kaori e conhece o acidente do passado dela com a mãe.

Yuki's teacher Jun Inoue, passes his test answers around the class as punishment for failing the recent math test. This forces Yuki to seek math tutelage from Kaori, who happily agrees and takes him, Shogo and Saki over to her house that evening to study. At Kaori's house the group meets her cheerful mother Shiho Fujimiya after which they settle down to work, with Yuki and Saki making slow progress. After some time, they procrastinate a bit when Kaori has trouble interacting with Shogo due to his intimidating demeanor, with Saki and Yuki trying to help the pair become closer. However in the end, the pair acknowledge each other as friends since they already hang out together. The next day Shiho asks Yuki to meet her at the park after school where she elaborates on Kaori's mental condition. Shiho explains that Kaori was hospitalized after being involved in a car accident and despite having no brain damage, she seemed to have repressed the memories of her friends after the accident for some reason. The next day, Yuki passes his test and talks to Kaori in class for the first time, making her happy. Seeing Kaori smile, Yuki resolves to continue becoming her friend over and over again as the weeks roll by. (Source: Wikipedia)
