12화: 유우지가 행동을 바꾸고 카즈키가 10년 전 편지를 되돌아본다

12

Yuuji stops his raunchy and perverted action towards all women. But doing this caused him to act depressed and tired, while Yuuji's friends try to figure out why he's doing this, Kazuki figures that it may be because of her that Yuuji became like this. Although originally Kazuki liked the 'old' Yuuji back, she remembers that the 'old' Yuuji is more similar to the present Yuuji. So Kazuki tries to remember what she wrote to Yuuji in the letter 10 years ago and finally comes to a conclusion. (Source: Wikipedia)
