I want to watch a drama where Male Lead and Female Lead get married early in the drama. But Female Lead doesn't want to get married. But she is forced to marry due to some or the other reasons. And Male Lead struggles to win her love. At first he may be rude but later turns into loving and caring husband which melts Female Lead's heart. Female Lead may be cold outside but she has a warm heart.
In Oh My General, they get married in like episode 1 or 2. He's a prince and she's an army general. She wants to get married (not to him particularly, she just wants to be married) and she loves him first, but otherwise it's exactly what you're looking for.
