As Daikichi continues to juggle work with raising a teenager, Rin
struggles with the relationship between her and Kouki, her childhood
friend. The last ten years have brought about a variety of changes to
their friendship-some subtle, some not so. Kouki may always have been
head over heels for Rin, but the choices he's made in the past seem to
have put a wedge between them. And when a scorned ex sets her sights
anew on Rin as the object of her rage, the tricks up this girl's sleeve
threaten to nip Kouki's potential romance with Rin in the bud for good.
As Rin's sixteenth birthday approaches, will there be cause for
celebration? Or will Daikichi have a crisis of the heart on his hands?!
