I love watching Cdramas but I hate evil and scheming 2nd Female lead tho I'm completely alright with evil 2nd male lead. Infact, I enjoy watching them. Maybe it's about how they're written. 

So I'm looking for Cdramas with a love triangle between (One female and two male) but no second female lead. Even if there's one, she isn't evil at all. 

Here are some such dramas that I really loved:

You Complete Me (no 2nd fl) 

Jun Jiu Ling (no 2nd fl) 

Love Me If You Dare (no 2nd fl) 

Lie to love (tho had a 2fl but she wasn't evil mostly) 

The Confidence (almost no 2fl)

I'm open to every genre, but should have a love triangle.

Cdramas with a love triangle between (One female and two male) but no second female lead.

C dramas with M/F/M love triangles and no SFLs, especially not evil ones (unless they were so minor that I have completely forgotten about them):

  • Bromance
  • Go Go Squid!
  • Across the Ocean to See You
  • The Eternal Love Season 2 - Note that the main two guys in the love triangle with the FL in Season 2 are actually two versions of the same person (the ML). Season 1 also sort of had a M/F/M love triangle, but it was a bit complicated with the FL's soul sharing another woman's body. Also the ML had concubines but they were very minor characters and he had zero interest in them.

There's an evil secondary female character, but she's not after the ML or the SML (the men in the M/F/M love triangle with the FL):

  • Sound of the Desert - A secondary female character tries to seduce the Emperor (not the ML or the SML) and betrays the FL. Another secondary female character is put in a situation where she's supposed to trap the ML into marrying her, but she chooses another man and they both end up being friends with the FL and ML
  • Go Ahead - This should probably be in the first list, but the ML's mother is just so awful. Absolutely loathed her
  • The Imperial Doctress - IIRC, the Empress Dowager is evil, but the ML's wife (Empress - not the FL) is not.
  • A Love So Beautiful - I don't really remember anything about the SFL but IIRC she was the FL's friend and dated a guy who wasn't the ML or the SML.  
  • Oh My General - The ML had other wives who did some mild plotting against the FL at first, but quickly ended up liking her more than their husband. I dropped this drama so it's possible that an evil SFL might show up later on.

@AH I'm being unable to quote your reply. But thank you so much for this list. Gonna try these soon. 

I have only one title at the top of my head which doesn’t include scheming 2FLs.

  • Warm on a Cold Night
