Classmates Minus (2021) on Netflix

Four high school buddies -- a director, a temp worker, an insurance salesman, and a paper craftsman -- grapple with unfulfilled dreams amid middle age ennui.

This is a story about four high school classmates. The storylines are intertwined with one another. Here are a middle-aged director who is frustrated with his undiscovered talents, a hard-working white-collar worker who is depressed about his lack of achievement, an idle part-timer at the Household Registration Office who is hesitant about love and a paper offering maker who is able to communicate with the dead.
