Looking for a manga (I vaguely remember the plot)

[Ragne]

Ops, I had promised I wouldn't ask for any other recs/manga but I just remembered of a manga that I started reading but never finished (also if I don't remember why, maybe I couldn't find the rest?)

Unfortunately I only vaguely remember the plot.

 

I remember that there was a vampire (or a demon?) following this guy home and basically falling in love with him and I think the human was quite shocked of him being a vampire (or demon?) and there was something about the vampire/demon protecting him from others vampires/demons. Gosh, I wish I could remember more! I also remember that, at least in the first part, the story had a light humorous mood.

could it be:

Koyoi wa Kimi to Chi no Kisu by tateno makoto
