Moonlight Chicken (2023)

Both have themes of cheating/infidelity, if you like these types of themes you'll probably like this one too, has 12 episodes that are like 30 minutes long, makes you feel bad about some of the characters.

Gemini and Fourth (the main actors of My Love Mix-Up!) are a couple in Moonlight Chicken as well. Although they are the side couple, they have a lot of scenes and have a beautifully written storyline.

Both of these BL dramas speak to the harsh reality of broken long-term relationships. How eventually resentments may build-up and become unsurmountable without the proper relationship practices in place to address them. It leaves both parties in an ambiguous state fueled by nostalgia, past fondness and care, and the desire to make a new start.
