AUthor-KUn or AK is a virus or malware that doesn't act like one, she's saralin's girlfriend (flaky and lammy Don't exist here sadly) both sides of AUthor-KUn are matching  the characters that sometimes represent her state, sometimes AUthor-KUn may have tantrums about how useless she is(witch saralin say is not true) she is a reference to ENA a character from joel G, AUthor-KUn isn't a malware like ENA since she dates an anti-virus(saralin or Sara) so yeah she dates an anti-virus and they both like each other
