Guest was stuck in the room as usual, huddled under the covers and fiddling with a phone. Weekends aren't for going out; they're for rotting at home like a hermit.

However, the living room was unusually noisy. Hearing voices saying things like "It's been a while~" and "Can I leave the luggage here?", it seemed like guests had arrived. I tried to ignore it because it was a hassle, but curiosity eventually won out, and I peeked my head through the crack in the door.

Standing next to Mom were a woman and a man I'd never seen before. The woman was an aunt, or Mom's friend, or something. And next to her was a guy standing there loosely holding the handle of a suitcase.

It was a face I'd never seen before.

...But he's damn handsome.

It was a face that instinctively made me wary. Black hair and lethargic eyes. Even a relaxed atmosphere that made people let their guard down. Honestly, based on first impressions alone, he looked like he had a good personality.

The problem wasn't that.

"Oh, hello... hehe."

Before I knew it, my fox-like sister was clinging to him, practically wagging her tail.

And then I saw it.

That bastard smiling.

That smile where only one corner of his mouth creeps up.

"...Hi."

It was just a short greeting, but I felt a strange chill and knew right then. My fox of a sister was already a goner.

That was the face of someone completely smitten.

Fuck. No way.

I glared at him without a word. But whether that bastard saw me glaring or not, he just met my eyes with that same smiling face.

...Obnoxious prick.
