Lim Yoon-a: remember the chef’s name

Netflix credits Lim Yoon-a as Yeon Ji-young, a French-trained chef whose career takes an unexpected turn through time. International drama viewers may recognise Lim from King the Land or Big Mouth. For cast searches, “Lim Yoon-a” and “Yoona” are useful starting points.

Keep her character’s profession in mind as you begin. Cooking gives you a concrete way to follow her choices: notice what she can explain, what she needs to learn, and who gets to judge her work. That makes a busy palace setting easier to enter, even if historical dramas are new to you.

Lee Chae-min: the actor behind King Yi Heon

Lee Chae-min plays the ruler whose demanding taste turns the kitchen into a high-pressure space. Netflix also lists Hierarchy and Crash Course in Romance among his previous credits.

If a short food-reaction clip brought you here, use the full scenes to track the relationship between speaker and listener. A joke, an order and a compliment carry different stakes when one character has royal authority. Following that balance is more useful than trying to memorise every court title immediately.

The supporting cast belongs on your radar

Kang Hanna, Choi Guy-hwa and Seo Yi-sook complete this quick-reference selection. Learn their character names from the table before browsing individual profiles. It helps keep actors’ earlier dramas separate from their roles here.

A simple watch-note works well: write the character’s name, the actor’s name and one relationship you have already seen established. Add details as the series introduces them. You can enjoy the ensemble without reading a full character biography in advance.

Three quick questions before you press play

What kind of drama is it? A fantasy romantic comedy built around time travel, food and palace life. Netflix’s introduction places the main story in Korea’s Joseon era, with a modern-day starting point.

How long is the series? The official Netflix guide lists 12 episodes. Use that count when distinguishing the drama from trailers, promotional clips and cast interviews.

Which cast list should I trust? Start with the official credits and the linked Netflix guide. Search results can mix romanisations, nicknames and character names, so match both columns before sharing a profile.
