Sayonara Note

"Taku-chan is my hero." The cheerful and caring Takumasa and the quiet Ken: there's a deep reason why these two started exchanging diaries, although it may seem childish. They've been doing it for five years and now it has become their special daily routine, which connects them to each other. That's why they should've known everything about each other… but Takumasa is surprised to hear from his classmate that Ken's in love! *There is an extra about another couple that is still untranslated.
