Sorta weird. This is about a "beastkin" named Momo, who turns into a lion when he gets excited, and is dating another man named Ryuusei who works at a cafe with him. This manga is basically all about their relationship and about how they deal with Momo's transformation. My biggest problem with this was seeing repeated sex scenes of Ryuusei having sex with a lion. It's a bit too weird for me.
