Perfect Crown

21세기 대군부인

South Korea · 2026 · 12 episodes

Sarcastic Warning: Contains Maximum Tropes. In this highly predictable alternate-universe setup, our heroine somehow ends up entering a contract marriage with a melancholic, title-rich but cash-poor prince just to secure a noble title. It's the classic drama bingo of emotionally repressed royals and ultra-wealthy commoners finding true love through legal loopholes!
