Toritan: Birds of a Feather, Vol. 2 (Yaoi Manga) — Kotetsuko Yamamoto

Ever since he was a child, private detective Inusaki has had the unenviable talent of being able to communicate with birds. And even though he's never liked birds, he somehow ends up getting his heart broken by one! Conveniently there to pick up the pieces, though, is his landlady's son, Mitsuru, whose voice sounds suspiciously like that of the fowl heartbreaker, Kuro. And it's not long before Mitsuru confesses his feelings to the clueless detective, even landing a quick peck. Will Inusaki the private dick ever stop brooding long enough to get a clue?
