looking for some kdramas where ML and FL are on bad terms but end up locking each other

This is probably one of the most popular themes in kdramaland, thus there are a lot of recommendations.
Eg;
Her Private Life
Pinocchio (this is personally one of my most favorite dramas, truly a gem ;))
Crazy Love
Strong Woman Do Bong Soon
So I married an Anti Fan
Secret Garden

Hometown Cha Cha Cha!

Several Korean dramas feature where the male and female leads start on bad terms, often with animosity or conflict, but eventually develop a romantic relationship. Some examples I can include are : Secret Garden, where the leads initially clash due to their contrasting personalities and social status, What's Wrong with Secretary Kim?, where a CEO and his efficient secretary have a love-hate relationship.
