underrated dramas with no romance?

i'm in the mood for something REALLY underrated, but with little to no romance in it. it can be from any country, but preferably japan or china. it doesn't matter much to me as long as it's good. i'm not big on political or super slow dramas (unless you think they're worth it). also if possible, please only rec like 1-3 otherwise it gets a bit overwhelming lol. thank you!!!!

1. The lost tomb series (idk about underrated), but it's pretty good. There's a bit of  side character romance in the fifth or sixth one, but I completely skipped it.

2. Detective Chinatown (parts 1, 2, and 3)

Aogeba Toutoshi 

Taiyou no Kisetsu 

Cinderella Formula 

isn't taiyou no kisetsu a romance? or does it just have limited romance?

 fanitha:

It has romance but the main theme is revenge

ooh okay sounds good, i love me a good revenge story
