Title: Offering My Neck To You
Yanchen has been living an odd life for the last decade. It's already strange enough that he is a vampire, but he's also raising a child that he never should have. After killing a werewolf, he discovered the werewolf he killed had a half-werewolf child. Feeling immense guilt for his actions, he takes in the child named Luoan. Werewolves and vampires are natural enemies, and having a half-werewolf around is even more dangerous since their blood has unique properties that empower vampires. Regardless, Yanchen does everything he can to raise Luoan to be an upstanding and strong young man.
Things are a bit complicated. Because Yanchen is immortal, his appearance never changes. To protect his family, they have to move every three to four years to avoid suspicion, but as Luoan gets older and older, it's harder and harder for Yanchen to be able to play his guardian. Things come to a head when the new school Luoan moves to happens to also have other werewolves attending, and they recognize Luoan as one of their own immediately. While Luoan wants to learn more about himself and where he came from, he doesn't want to be separated from Yanchen.
But Yanchen, seeing Luoan among his kind, wonders if it wouldn't be better for the half-werewolf to be with them. While Yanchen and Luoan struggle to come to terms with their family foundation weakening, a deadly threat lurks in the darkness. Half-werewolves are ideal for vampires, and with more eyes on Luoan, it's only a matter of time before the other vampires come out to get a taste of that power. Can Yanchen protect Luoan? Or will he have to give up Luoan to ensure his safety, even if it means living life alone once more?
