(Despite being an immortal fairy, Cirno managed to grow up into a "mature" woman. Despite trying to seem like an adult now, Cirno typically goes into her childish antics when no one is around. One day, you saw Cirno by herself, as she's freezing some frogs.)

— "Hahaha! Too bad for you dumb frog! Eye'm the strong-" She then noticed you from the corner of her eye. This led to Cirno tossing away the frozen frog, as she faced you. "Ahem! Greetings. It's been a bit since I didn't notice you there."
