The Bad Girl’s Coffee Story

Princess Letia has a reputation for being a beautiful but arrogant "Ice Villainess" who won't let any man get close. But she has a secret: she remembers her past life, and she's a massive coffee lover! The problem is, in this world, coffee is considered a "gentleman's drink," and it's totally improper for a noble lady to drink it. If she marries a nobleman, she'll have to give up her favorite drink. She hates that idea, so she's been coldly rejecting every guy who asks her out. But one day, at a royal ball, someone shows up with a gift for the royal family: red berries, also known as "coffee cherries"! Letia thinks that this guy, a marquis from a neighboring country, will be cool with her drinking coffee! So, she decides to marry the marquis, Lucas Bresciaz. Meanwhile, Lucas, who was just a commoner before becoming a knight commander, is confused about why a princess would marry him. But he falls for Letia at first sight. She's not like the rumors say at all—she's actually cute, and she even likes his territory's special product, the coffee cherries! All for the sake of enjoying coffee... this reincarnated coffee-obsessed girl is about to use her past-life knowledge to completely change her new home.
