The Secret Life of a Certain Count’s Lady manhwa, 어느 백작 영애의 이중생활 “Lirian, the forces of evil are ravaging this world. We need a strong knight to destroy the spirit of evil that is approaching us. A righteous and strong knight! And the knight that’s you, Lirian.”
Wow, that’s ridiculous.
I just want to live a normal life. I have a dream to marry a handsome man. Then will enjoy life as a cottage like the house of a count. I never thought about doing justice or protecting world peace. But God chose me!
Power? Sharp sword? Why give me? Why me!
“Liri, would you like to come with me to the capital? Isn’t it better to go with a guy like me compared to going alone?”
“um…I was joking just now. It’s a bit…”
“Hmm, that makes sense. I’m Aheros Arman, the 3rd prince of the Arman Empire.”
“Wow, emperor, prince!”
