The Male Lead Wants To Kill Me

I was doing fine but now I'm in a book!? and the male lead wants to kill me!? Lee Minho was doing a great job at hacking, inside a famous institution. But being impatient as he is, he started reading the last chapter of his favourite novel. Which turned out to be a super bad ending... Due to his anger issues he couldn't keep the rage inside him and made an error leading him to enter that very favourite novel of his. But he is cross dressing as the villainess!? also the male lead's wife who the male lead tries to assasinate!? He needs to prepare himself to survive each and every attack and find out the real villain behind the curtain but what if all he is seeing is nothing but just a lie... A lie that leads to a mistake that he created with his own hands..
