I Became A Tyrant’s Maid

Youour Highness- That is absurd!! "Youour Highness, did you just cough-!!!" "It's doomed! I've been transmigrated to another world! As an extra chambermaid from a 19+ imperovished novel from the early 2000s!" For now, I'm trying my best not to upset the male lead's temper so I can survive and return home... "Youour Highness! Please have mercy!" "Youour Highness! That is such an absurd thing to say!" "Could you please stop with that damn antiquated language?!" Seems like the etiquette here is a bit different from what I know... Anyway, after defeating an assassin and taking an arrow for him, I feel like I've become somewhat closer to the male lead. The ominous journal that seems to understand my words, and the male lead, who orders me around, seems a bit fishy too. "Can I survive here and return home?"
