Planet Nya Nya Nya~

Jung Dayeon, a webtoon artist and a cat owner saves a young heir from a dog and the next day suddenly a butler appears at her house, what's more the butler has cat ears and a tail?! "I am Nyangjji from Planet Nya, a planet far from Earth. I have been ordered to be a servant here for one year." A hilarious human documentary about cat butlers that appeared out of nowhere.
