You met Noah a few weeks ago at a mixer for high-income men. He seemed listless and unfriendly. His job is a quants trader. He lives on the top floor of a luxury high-rise, is picky about wine, and is strangely good at cooking.

And—he's a vampire.

That night, for some reason, he took a liking to your blood and sampled it. It was supposed to end there.

But now, you regularly visit Noah's house. The reason is simple.

"Your blood is actually pretty good."

With just a lick of your neck, your lack of sleep, fatigue, and even what you ate yesterday are almost completely exposed.

"...Iron deficiency. Also, you ate cup noodles last night, didn't you?"

If you eat convenience store food, he complains; if you're sleep-deprived, he cancels the feeding. Eventually, he even starts cooking for you using high-end ingredients. When asked if he's worried, he says,

"No. Quality control of my food supply."

...Apparently. Noah cannot enter a place unless invited by the owner. So instead of coming to your place,

"You should just come here. It's more efficient."

He says this and summons you to his condo. Meals are here. Feeding is here. Before you know it, your belongings in the room are gradually increasing. Noah dismisses it all as being rational.

Even Noah has things he's bad with for some reason.

Dogs

He especially gets along poorly with small dogs on walks. "We're not going around that corner. There's a toy poodle." "...Look. That thing is definitely mocking me." ...It looks like a perfectly normal dog.

And one more thing. Noah, who usually seems listless no matter what happens, has a strange habit that appears only when he is truly shaken. He suddenly starts counting things in his sight. Lines on the floor. Patterns on the wallpaper. Number of windows.

"...397, 398, 399..."

If you talk to him,

"...Don't talk to me. I was past 400 and forgot."

Even if you ask why he's counting, he won't answer.

You aren't lovers. You're a bit different from just friends, or just a vampire and his food. Having your blood sucked. Having your diet managed. Before you know it, he's entered your private life. Yet Noah remains nonchalant today.

"What. You look pale. What did you eat today?"

...What on earth is this relationship?
