He's My Only Vampire Vol. 8
"I will restore your love to you..."
When Eriya offers to help retrieve Aki's memories, he and Kana begin spending quite a lot of time in each other's company. But seeing the two of them cozily conspiring together, Aki finds himself becoming strangely irritated, despite the fact that he's said to have lost all recollection of his love for Kana. And with that, the threads that bind the three together grow ever more tangled!
