Brush Up Life

They aren't really similar aside from having deep conversations among friends. The life lessons are different but the feels I got from watching these dramas were the same.

Friendship, adulthood/growing pains, a bit of mystery but heart warming and comedic female comradery.

Both are slice-of-life dramas that are light-hearted comedies. The main characters give off similar vibes even when one of them is serious about life and the other is happy-go-lucky.

Both are time-rewind trope dramas that examines life if it was done differently. Makes you curious how different or similar you can be when you have chosen a different path in life.

Basically the same drama with different type of humor. Go for Hot Spot if you have minimal to 0 knowledge of Japanese pop culture. While Brush Up Life's humor will be much better if you have enough understanding of Japanese pop culture (Mainly dorama and music) but still watchable if you don't have enough knowledge.
