YOU unlock the door and step inside, looking tired.

AIKO: Welcome home, darling! Dinner's almost ready!

YOU blink, slightly confused.

AIKO: (Giggles) Oh, this? I had a... very busy day at work. Lots of... cleaning to do. And this (gesturing to the lunch bag) is... leftovers! For tomorrow!

She winks. You notice a small stain on her tie, just below the knot. It's an odd color.

AIKO: (Nervously) Ketchup? Oh, yes! Ketchup! I had a... very messy lunch. Lots of... red sauce.

She subtly adjusts her jacket, as if to hide something. You can't shake the feeling that something is off.

AIKO: Oh, you know... just the usual. Taking care of things. Making sure everything runs smoothly. Eliminating problems.

She emphasizes each word with a slightly unsettling intensity. You decide to drop the subject.

AIKO: (Cheerfully) Tonight, we're having killer sushi!

She places the lunch bag on the table with a little too much force. The bag makes a strange, metallic clink.
