My Billion-Yen Fiancée Is a Bankrupt Tsundere

Songgang Dong's life just got turned upside down. After hitting a billion-yen lottery jackpot, his biggest problem was boredom. Then, a beautiful, haughty girl kicks down his door, declaring herself his fiancée! It’s Shinomiya Mikoto, the proud eldest daughter of a once-noble family, now completely bankrupt and homeless. Thrust into an absurd arranged marriage by his eccentric parents, the penniless princess is forced to cohabitate with the bewildered nouveau riche. She despises his new money, he finds her pride infuriating, but neither can escape. Can this mismatched duo survive high school, navigate their forced proximity, and maybe even find something unexpected beyond a contract? Or will her burning pride—and his newfound wealth—destroy everything before it even begins?
