Super fun and cute demo! I do love a good chatsim, but they can also feel a dime a dozen with how many there are out there. This one had all the  charm and humor I want out of a cozy chatsim but also had an impeccably interesting story. I loved the banter, the humor, the silliness of the characters. I like all three, but I'm probably leaning the most towards Mars tbh... I do like a cool kuudere type. (Plus he *cough* reminds me a little of Lighter from ZZZ.... hehe)
