A girl wakes up with a dinosaur in her apartment and decides that's just her life now. The show doesn't treat this as a problem to solve or a mystery to unravel, it's just two roommates existing together, buying groceries and watching TV like the dinosaur has always been there. The comedy lives in that complete acceptance, in the smallest moments of domesticity with something that should be impossible, and it never needs a bigger reason than that.

Kaede wakes up one morning after a heavy night of drinking and finds a real dinosaur in her home, a guest she brought back with her while drunk. Rather than panic, she simply accepts the new arrangement. What follows is a low-key comedy about two unlikely housemates sharing ordinary days: eating, watching TV and going shopping together. The dinosaur cannot speak but seems clever, handles instant ramen just fine, and is terrified of cats, even though cats adore him. The humor comes from treating a dinosaur like a normal roommate, and Kaede's easygoing attitude shapes every gag as she slowly learns more about her unusual companion.
