Cara me stessa (2020)

Very similar drama: 3 main characters, 1 is a devoted mother, 1 is young and lost in life, there's a cheating scandal, some entrepreneurship, an insight into a rural Chinese hometown
Nothing But Thirty is my favorite of all CDramas ever made, and To Dear Myself is the most similar drama that I've found

Both are female centric dramas, although To Dear Myself is a lot heavier on the heart/they take a more realistic and less idealized viewpoint on life.
