I know Kirins are often called "oriental unicorns" and I know stereotypical otakus are worthy of that same moniker, but it's still quite a surprise...
About that, I believe there to be a mistranslation in the sentence: it's not "her" who will be arrested, but "you" (Sunghoon), since the crime is, paraphrasing (as I don't know the real name), "indecent conduct with a highschool girl" (with "highschool girl" seemingly being interpreed as both "girl of highschool age" and "woman dressed in a highschool uniform").
