“Periklytcha”

A purple-haired girl with cat ears looks forward with glowing eyes, then the scene cuts to a pink-haired boy with a confident expression, followed by a pink-haired girl with closed eyes and a halo above her head in a library, then the boy turns to face a white-haired girl who looks at him with a concerned expression, and finally the boy looks thoughtful with his hand on his chin. The setting is a library with bookshelves in the background.
