Kdramas With Happy Ending, Chemistry, Etc...

Please recommend me recent (2020-present) K-dramas where:

• There is a happy ending (no open endings)
• There is chemistry between the main leads
• It focuses on the main couple/leads, as in, I don't want a lot of back/sidestories for supporting roles
• Has either one or more of these tropes: hate/love, bickering relationship, ML has secret crush on FL, enemies to lovers, love triangle, rich ML/poor FL, hidden identity, cold ML/warm FL, jealous ML

I'm currently watching and liking Strangers Again, and the last K-drama I watched and loved is A Business Proposal.

 AH :

• The King's Affection 
  • love triangle
  • hidden identity
  • secret crush (but he confesses his feelings pretty quickly)
  • a little bit of bickering and hate/love
• Hometown Cha-Cha-Cha
  • love triangle
  • bickering
  • very slight hate/love
  • there is some focus on secondary character story lines here and there
• Adult Trainee (episode 3 - 5 only)
  • bickering
  • ML has a secret crush on the FL and, iirc, jealous ML a little bit
  • I'd say there are some good chemistry moments, but there are also plenty of awkward moments (that are supposed to be that way), so it's not intense chemistry all the time
• Soundtrack #1
  • slight bickering
  • ML has a secret crush on the FL

Thankyou AH!! ^^
