Please, suggest some crime/romance/action stuff I could watch next - preferably no love triangles

Hey. This is my list and I really have no idea of what to watch next if there's anything I could without getting angry:

Sylar_Rose's Drama List - MyDramaList 

What I like:
- action series (always good but not necessary)
- criminal series (my favourite ones)
- romance with no love triangle (I really hate those but as you see - I have enjoyed some series with minor ones - I'm aware it's hard finding anything without a love triangle)
- strong and normal ML (K2, Lawless Lawyer, Hello Monster, such stuff)
- happy ending (totally crucial, I do not want anything without it)

What I hate:
- indecisive FL & ML
- real love triangles
- death of ML/FL
- when there's no happy ending

It may be Korean, Japanese, Chinese drama, I do not care. Thanks for any suggestions! :-)

• Flower of evil+1
• Vincenzo +1
• My Name
• When the Weather Is Fine (not action but crime mystery element)
• Are You Human Too?
• Blue Birthday(if you looking for a light and quick watch- school drama+time travel+Crime )
• Definitely Not Today(super short bonnie and Clyde type)
• When the Camellia Blooms (not my fav but a lot of people like this)
• While You Were Sleeping(not really a love triangle tbh but fits what you want)

Almost no romance(or hinted) but otherwise fits

• Doctor Prisoner
• Imawa no Kuni no Alice
• Life on Mars
• Taxi Driver
• S.C.I
• The Devil Judge

Flower of evil+1

+1

there are good dramas, some of them was mentioned here, some of them I saw in your list but really really BEST ever drama in Crime/action/romance is "Cruel City", it's so high level no other will compare to it... you would love everything in it, twists and turns, unexpacted surprises, character developments, action and interesting events TILL the end (many dramas have good start but then goes down, but it was perfect 20 episodes), you never know what will happen next, who is whose ally or enemy, mafia, undercover cops and gray characters, I mean no one is fully good and only few fully bad, this drama is complex and not usual cliche black/white sotry. Many multilayered characters and complex relationships but ML is best, someone like K2 + more smart and more dark, anti hero/criminal authority. 

+ one of most amazing romance (though it's kind of side story not main, but still one of best and emotional romance I've seen, with hot chemistry).

only problem - not happy ending... I don't love it either but many serious great dramas don't have happy ending unfortunately ... but not watching this drama especially when you love that genre is just so big waste... 

p.s. after "Cruel City" I'm always hungry for something like this drama, I hoped few times (for example when I tried Vincenzo, also "My beautiful bride") but every time after few episodes I realize that this isn't even close...

p.p.s. can I ask about your nick name, why Sylar (because I remember one Sylar, very old American  tv series villain I loved)

Vagabond    

Gotta watch Vagabond :) so much action, so much crime and corruption, but very very subtle love relationship.
