Not a Peep!

With the press of a button, Yu Sol's life is about to turn upside down. When a mysterious post with the power to transport the user to their favorite fictional universe pops up on his feed, Sol clicks "share" and falls asleep...only to awake the next day as a round, winged puffball! Try to speak as he might, he can only mutter one word- er, sound: "Peep!" With his new avian appearance, Sol must navigate the land of Sevon under the guiding hand of his new (strikingly handsome) owner, Karhan Barthés, while trying to find a way back to world from which he came.
