About a boy who thinks he might be a vampire because he wants to bite his friend but begins to realize that he's actually in love with his friend.

I had it bookmarked on Manga Toshokan ages ago, but now that MT is gone I can't find the name of it anywhere. Any help you could provide would be greatly appreciated!

Through the help of a user on another site, I've found the manga I was looking for. Hatsuai is the name of it, in case anyone's interested. It's awesome.
