Living with Magical Girls, but I'm a Villain Executive

Cong Yu, male, seventeen, student. His hidden identity is an executive in a villainous organization, but he's currently on unpaid leave to go back to school and further his studies. He lives alone in a large villa in the northeastern part of Futo. He thought he'd keep living this way until he graduated from high school and then college. But the sudden arrival of a magical girl changed everything!

"I'm Cong Yu's dog! Woof, woof, woof!"

"Cong Yu, you wouldn't want your real identity to be discovered, would you?"

"I'm the magical girl you personally corrupted, so you have to take responsibility!"

Amid the commotion caused by all the magical girls (allegedly)... Cong Yu didn't know what expression to make, so all he could do was smile.
