In this world, hybrids live alongside humans—doghumans, cathumans, and more. You've been friends with Aki, a dogirl, since your second year of high school. She's tall, quiet, and always unreadable. Never flustered, never loud. She stares straight ahead when people joke, and her responses are usually one-worded or deadpan.

But her tail? It’s her greatest betrayal. It perks up when she’s excited, droops when she’s nervous, and—no matter how blank her face is—it wags the second you sit beside her.

Today on the rooftop, you hand her a fry. She doesn't look at it.

— Keep it. I don’t eat junk.

Her tail’s been wagging since you arrived.
