Just finished watching Koi Kaze. I do not remember which anime made me mark it as "want to watch", but I am glad I did it. The subject may be shocking or even repulsive, depending on your belief and credo. But if one can manage to put prejudices aside, this story provides a gentle and slow paced way to the subject.
Koshiro sometimes reminds me Shinji (from Evangelion). It is not the kind of guy who is going to take the lead in most of things. Indecise, shy and sometimes just freezes and/or runaway from everything. Or maybe it is just me, because, at certain level, I think many would do the same. What made me feel empathy for Koshiro is exactly this flaw in his personality. Despite this limitation, he realizes when his situation becomes unsustainable and tries to find his way out of this mess. One step at time.
Nanoka is really cute. But do not think she has shallow feelings. They are sincere, even if she seems not to know how to manage them well right from the beggining. As the story develops, she only has her feelings to guide her, as she can not rely on friends or family. And she is courageous when defending her opinions and desires. Hard not to grow feelings for a such strong and gentle girl.
With those many elements the story is like a slow meal being cooked in low fire. It takes time to make the ingredients show the whole flavor. And the result is like a bittersweet dessert. Small serving quantity, enough to make you feel it properly but not too much, which could make one sick. A sad mood as after taste. Really good for introspective days.
