This is more gonna be a warning rather than a review.

The Interest of Love is for people who are into psychology and sociology, melos and slow burns. This is not a conventional romance but a romance depicting modern korean society. Besides, the genre is noir, so don't be too surprised. This is the opposite of what you could call "dreamy escape" from the K-Dramas people love and are accustomed to. If you want to learn about the society and adult relationships in Korea, look no further. Although the setting is Korean, many adults around the world could relate to this story, at least to some extent. In fact, The Interest of Love is the adaptation of a critically-acclaimed novel in Korea, named "Understanding Love" which is the drama's korean title. The adaptation was also acclaimed by critics and recognized as one of the best K-Dramas of 2022 by industry experts. The novel concludes at episode 12, which likely wouldn't have been adapted into the TV series for reasons that will become clear once you see how the episode ends. The remainder of the story was written by the screenwriter, and the ending feels fitting.

Mantra by everyone who signed up for The Interest of Love’s chaos: “Everyone is flawed. I'm gonna sit and watch.”

Get it or not, The Interest of Love is a masterclass in directing, acting and writing. The storytelling and attention to detail are really clever, and the mundane beauty of this drama is something that no other can match.

Overall, a very unusual and philosophical show with a unique setting.
