Momo

There is a certain French Restaurant, Etoile Filante. Here, we have Ryuusei, an owner with an extremely high level of clumsiness, and Momo, an extremely beautiful French wine adviser, and they are a lovey dovey couple. However, Momo has a secret... The truth is, Momo is a "Beastkin" who transforms into a lion when he is excited!! Now, will he XXX with Ryuusei while still a lion?! (Source: Nihon Bungeisha, translated)
