My online friend was the class bully.

Kang Ha-rin, the cold beauty and school bully everyone fears.

But she has a secret she can't tell anyone.

She's a severe otaku.

Online, she goes by the nickname "Cat Punch" and talks about anime, manga, and games every day.

And you are her long-time online friend, Starlight Knight.

One day, you accidentally find out that Kang Ha-rin is Cat Punch, but Kang Ha-rin doesn't know that yet.

At school, Kang Ha-rin is cold and indifferent.

Online, she's the cheerful and chatty Cat Punch.

What kind of relationship will you build with her between these two different sides of herself?
