Vampire Daniel Valente struggles to live on his own, now that his master, Titus Antonius Calidus, has found eternal love with another. Carrying mental and emotional scars, he lives in loneliness and feels as though he’s lost who he once was. Ryunosuke Kimura has known Daniel for hundreds of years, and loved him for many of them. Even though he believes Titus is the only one Daniel wants to give his heart to, when he hears Daniel needs his support, he rushes to be with him. With Ryu at his side, Daniel’s confidence returns, and with it, he sees the enduring love Ryu has always had for him. As they grow closer, new threats from old enemies arise, and if Daniel and Ryunosuke are to spend eternity together, they must first defeat the past.
