Spinoff of "Mujaki na Wanko to Nekokaburi"
Seiji is a 39 year old, single, cat-dad who runs his family's old shop. Unexpectedly, he runs into a figure from his past—Shin, a man ten years his junior, whom he met when he was still a police officer at 27. Shin used to be something of a delinquent at 17, so Seiji always made sure to keep an eye out for him and the two became friends until Shin left town for college. When they reunite, Shin has followed in Seiji's footsteps, only to discover that Seiji left the force some time before Shin joined, much like two ships passing in the night~
The two pick up where they left off, but when Seiji mentions in jest that since he's been single so long, he may as well go for men, it prompts a rather shocking response from Shin, who kisses him and confesses that he's been in love with Seiji for the past ten years!
