Doutei Hitsuji to Abazure Ookami

Tanaka, a typical salaryman with no romantic experience, is attacked while walking home through a park. He is saved by Kira, a young man who then demands payment in an unexpected way. After losing his virginity, Tanaka tries to move on, but Kira continues to appear each night along his route home. Kira's persistent presence makes it difficult for Tanaka to forget what happened. The situation creates an uneasy dynamic between the two as Kira's interest in Tanaka seems to go beyond the initial encounter.
