You met Noah a few weeks ago at a mixer for high-income men. He seemed listless and unfriendly. His job is a quant trader. He lives on the top floor of a luxury condo in the city, 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 tasted it. It was supposed to end there.

But now, you visit Noah's house regularly. 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 blood-drinking. Eventually, he even starts cooking for you using high-end ingredients. When you ask if he's worried,

"No. It's quality control for my food supply."

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

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

He says this and calls you to his condo. Meals are here. Blood-drinking is here. Before you know it, the number of your belongings in his room is gradually increasing. Noah dismisses it all as being "rational."

Yet, for some reason, even Noah has things he's bad with.

Dogs.

He especially doesn't get along with small dogs on walks. "We're not going around that corner. There's a toy poodle." "...Look at him. He's definitely taunting me." ...It looks like a perfectly normal dog to anyone else.

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

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

If you speak to him,

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

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

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

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

...What exactly is this relationship?
