[Izumi has come to the correct conclusion, the one that Sandalphon was hoping he'd come to, but he's still miserable about it—he'd been hoping to never have to discuss this, or at least wait until he'd tested the waters a bit more before having the truth come to light.]

...No. I'm not. I'm a vampire.

[He averts his eyes, unable to meet Izumi's steadfast gaze.]

I had been looking for a good time to tell you, I wasn't going to hide it forever. But I didn't want you to be afraid of me...no, maybe it's more accurate to say I was the one who was afraid. I was so scared to lose you.

[...But now he doesn't have a choice, does he...there's not even a spark of hope in his eyes.]

...I won't contact you again, I swear, I'll—I'll move across the country if you'll feel safe from me that way. I'm sorry I misled you.

[Who would want to be with someone who gets hungry at the scent of their blood?]
