Title Concept: Unexpectedly Married to a Billionaire
These C-drama movies often follow the whirlwind romance between an ordinary woman—often strong-willed, independent, or facing personal struggles—and an aloof yet handsome billionaire with a hidden soft side. A twist of fate, such as a contractual marriage, mistaken identity, or a forced union due to family pressure, leads them into an unexpected marriage. What begins as a cold or transactional relationship gradually warms up as secrets unfold, emotional walls break down, and love blossoms amid luxury, corporate power struggles, and heartfelt personal growth.
