I loved the second story, where a bisexual playboy that likes cute people gets confesed by his BFF. His tall, grumpy, "totally not his type", also a tachi, BFF. And that's how or protagonist realizes that when your partner is the preson you care about most in the world, everything they do is really cute.

"The Buddhist zodiac inspires this story about Masataka, a shrine priest who tends to all the animals in that zodiac and becomes possessed by each one during their respective month, acquiring their powers, and the cat god, Koma, and his protector, Koutarou, who suddenly show up at his shrine. The first story deals with the exclusion of cats from the Zodiac. The next ones deal with the mystery of Koutarou's appearance, the threat of an encroacher who wants to steal power, and the slow-paced evolution of their romance. "
