I know it has bdsm and fetish themes but the story is very mellow for me and subtly deep. I think this is the heatlhiest progression of love without being too fluffy or vanilla. It has the perfect mix. Both characters (Akihiko and Souhei) are very mature and well made individuals which fit the frame of the story perfectly.
Maaaan made me cry and laugh. Damn those vigorous movements.
