NAISHO DE ALLELUYA

Shuuichiro is a famous song-writer and a father to Botan from a failed marriage. Botan is lonely and asks if he can have a cat. Shuuichiro tells him no, but Botan brings one home anyway... a very human-looking cat who is actually a man who Shuuichiro slept with before named Umekichi! Will Umekichi get to stay? Will Shuuichiro figure out what Umekichi reminds him of his past? And will he sleep with him again even though he's Botan's pet?
