If he could only have one defeat CG in his life, Cheng Shi hoped it would be himself turned into a magical girl, not the childhood friend he had spent every day with, his big sister.
He'd only taken a job at a secret organization to pay off his debts. How did casually defeating a magical girl turn out to mean beating someone he knew?
Staring at the familiar face of the unconscious person before him, Cheng Shi's vision went black.
He couldn't let the organization discover he had betrayed them, and he couldn't let his big sister find out who he was either...
Then there was only one answer!
All he had to do was use his extensive office-drone experience to manipulate both the organization and his big sister into making her quit her dangerous magical-girl job, and everything would be fine!
Please, as long as you don't tell Sister Lin Xue, I'll do anything.
What? You want me to go on a date with you? Huh?
Cheng Shi's fate has long since become entangled with that of the many girls around him. Trapped in a whirlpool of emotions and destiny, no one can escape.
The two embrace: "These stolen moments of happiness... even one more second would be enough."
The white-haired girl sits at the head of the bed, sobbing softly: "If only I'd locked you up from the start. Then you could have belonged to me forever, right? I almost lost track of you."
The pink-haired girl points at a shooting star: "My love may not be pure, but I give it to you. Let the shooting star bear witness. Start over, even if we start over a hundred times. No matter how many choices there are, I'll always tell you I love you."
The green-haired girl cups her face in both hands: "My dear kindred, I've loved you for a long time. Since when? Hehe, you tell me?"
