Both are light, mostly fluffy romances with a seemingly cold ML who melts around the FL. Both feature adorable pets as supporting characters.

One of the mains works in the fashion industry.
......................................................................

FL is a shapeshifting cat/human who meets and ends up living with the human ML. Both dramas have a mostly fluffy feel.

Cat/human shapeshifting lead (ML vs. FL) meets human ML in cat form and ends up living with him.
.................................

Very different in tone and setting, but both feature delicious looking food/cooking and an enjoyable though seemingly mismatched romance between the leads.

Both feature mainly gorgeous shots of cooking/food (the food is basically a character) and seemingly mismatched but very compatible couple.

Both dramas feature "fish out of water" naïve non-human FLs who don't understand the human world. They meet the ML (in bare feet) who is kind hearted (JAF more obviously than TLOTBS) and helps them. In both, the FL can only love/be attached to one man in her lifetime. Both have seaside settings, umbrellas, and a similar tone and feel.

Very different in plot but both fuse the genres of horror, mystery, and romance with ghosts.
......................................................................

Very different in plot but similar elements of ghosts and a sweet somewhat teasing relationship between the main characters.

Both feature ghosts, mystery/horror elements, and a strong friendship that can be read as romantic but doesn't have to be between the leads.

Both are short dramas about the FL caught up in a situation involving ghosts and meeting the ML who helps her.

While different in setting and plot, both have horror. mystery, and romance as the genres and feature a ghost that haunts the FL because he loves her or wants to marry her.
