Suteneko no Ie – Nawo Inoue

A vampire who lives in complete isolation, Ed, one day finds an abandoned child named Phil on a whim. From then on, they live together. Saying he loves Ed, Phil grows innocently emotionally attached to the vampire. Meanwhile Ed grows perplexed by the passions awakened in him by the human. 

A nicely drawn story of a vampire and his human. Mostly shounen-ai with a dash of yaoi  but nothing too explicit.
