Subete Wasurete Shimau kara (2022)

While these shows don't have a lot in common when it comes to plot, but the leads (and their calm-ish demeanour), the overall vibe, indie music and cinematography make these dramas really similar otherwise.

Both productions feature male leads who are lost in their lives and spend their time looking for women they once loved. Both productions feature a narrator voiced by someone who's not the ML; both have a similar vibe and great soundtrack
