- It looks like a detective drama, but it's actually more psychology crime
- Have Haru on both

- Maki Yoko as a lead
- Women struggle on a men-dominated world
- Gay/bisexual character

And the opposite is true too.
Plus add with them Sassy go go / Cheer up
and Who are you? School 2015.
as the four of them revolve around a high school romance comedy drama with some love triangles maybe although it wasn't really a love triangle in school 2017.
But it is just that hi school love on has some supernature genre which is extra but it's still amazing.
and also the four of them has the concept of bulling in them which make the drama more intense.
These 4 dramas would be your favorites if you like the high school - youth - romance - comedy type of dramas,like really i adoreee them!
School 2013 is great too but there is no romance in it so i didn't mention it but it shows what hardships friends might face and so on so if romance is not the main genre that you're looking for, you may check out this one too as the bromance in it between Lee Jong Suk and Kim Woo Bin is so cutee.

Both dramas have law and politics as main plot. Defendant is more drama because the case itself involved the prosecutor life; in Stranger, the prosecutor's family is not involved on the case, his life is not the main plot.
Both have a reliable and strong female lead. In Defendant is the lawyer and in Stranger is the Lieutenant.
