Historically set Korean dramas. The main couple's personalities is similar, and the tone is relatively light and occasionally comedic.

Similar tone, historical setting, slow pace, and interesting characters. The ML's personality also seemed similar to me.

Historical setting, both are Korean dramas. ML and FL have a strong bond and good chemistry. ML becomes traumatized by the constant war. Surprising hopeful/happy ending after ML is wounded/near death and thought to be dead/possibly dead by FL.

Cross-dressing FL or ML, historical setting. ML loves the other regardless of gender.
.............................

Both are cozy short Korean dramas, set in school at the beginning, and focusing on soulmates (DMN takes this in a fantasy way). ML initially seems distant to the other ML or the FL.

Very different in tone, but both are historical Korean dramas with MLs whose job involves marriage and who have left or been forced to leave their noble class background.

Master/student relationship. Similar bittersweet, melancholy feel and tone.
....................................................

Nods to the fairytale, poor FL ends up living with rich guy(s) and falls in love with him/one of them. Similar tone and feel.

ML is a bully who undergoes character growth and change after meeting FL who he initially plays games with and bullies, but then slowly falls in love with her. ML is a student in both, but the FL is older in Promise Cinderella. Similar style of humor in the lighter scenes.

ML is a bully who undergoes character growth and change after meeting FL who he initially plays games with and bullies, but then slowly falls in love with her. ML is a student in both, but the FL is older in Promise Cinderella.

Different in tone but similar in characters and aesthetics. ML is a god like being, FL a human, and their relationship grows slowly. Also in the end, ML disappears, then returns as a human.

While very different in tone, there are similarities in characters. The SML is a gentle scholar and the ML initially appears as a villain, distrusted by the FL. Events occur that the FL is not expecting which cause her to fall for the ML and experience hardship.
