The Vampire Dreams of a Heart

Volume 1:
"He'll do it with anyone if asked, even with me."

It's not easy for college student Shuri to harbor affection for Hisato, a vampire who's been like a father to him, when Hisato will kiss, have sex with, and even whisper words of love to any who wishes for it. Wanting to become the "soulmate" that Hisato has been yearning for, Shuri is ruthlessly eliminating people getting close to him, but there's no end to people willing to give their blood and bodies to Hisato in return for the pleasure they get from getting their blood sucked...

Volume 2:
Kissing and blood-sucking are allowed, but not sex... Why? Detective Koichiro dotes on his cousin Enji, who calls himself an inhuman "vampire", even giving him blood whenever he wants. "If I die, you die. Is that what you want?" Enji, who desires not only his blood but Koichiro's entire existence, suggests it's time for them to grow apart... but will Koichiro accept that?
