Mystery/Crime/Suspense/Thriller drama with sismance

Hello! 

I’m looking for recommendations of dramas that have both sismance and a hint of suspense/mystery/crime etc? I have mostly seen sismance dramas that are romance/comedy and I was wondering if it’s possible to find something different! I have watched “The Evidence Tells” and  “A couple of mirrors”. 

Thank you!

Lies Hidden in my Garden - this one is a bit of a unique case. Both ladies are working with each other but also against one another. It is a very dark drama with lots of plot twists and turns. If you have seen Parasite then this is definitely going in that direction. 

Not necessarily a sismance, but a platonic relationship between a FL and a ML.

• Once Upon a Crime (movie)
• Maiden Holmes has a team (3 guys, 2 girls) that solve mysteries and the two ladies have a nice friendship (once the one FL gets over her crush when she thinks the other is a guy)
• and Love of Replica has twin sisters (kind of) who have a complicated relationship.
