Cute! Single father sleeps with a random guy, who then tries to blackmail him, even to the point of getting the father's son to bring him home as a "cat" (lots of implied neko jokes in here). Turns out that they're actually cousins that haven't seen each other since they were really little. The cousins part I wasn't too fond of because I'm not a fan of incest stories, though cousins is a bit distant at least, but the rest of this was too cute. Just a story fully of love!
