Bussetsu Hybrid

Keishin, the charming eldest son of the neighboring temple, is Souta's childhood friend and lover. Together they've had all kinds of wild sex! In order to inherit the temple, however, Keishin must go to the main temple and devote himself to training for three years. Souta is teary-eyed from loneliness, but is told nothing will change; he just has to be good and wait. But when Keishin comes back, he seems to have completely changed into an ordinary monk. Did he forget Souta along with his worldly regrets?
