After grandma's cat cafe closed down, Su Niannian took over.
She vowed to make this place the most cozy cat cafe in the city—until the laziest blue-silver gradient cat spoke.
"My name is Yin Yuan, the Lord of the Demon Realm."
"... You? The Lord of the Demon Realm?"
"Yes. Please get me a glass of water."
Su Niannian:...
From then on, her cat cafe painting style changed dramatically: milk tea party reporting information, monsters lining up to report, and a handsome silver-haired guy who claimed to be "very troublesome" who ate and drank in her shop every day.
And she actually became the most special existence in the demon world - the only human being who could make the demon king obey.
