Jealousy Incarnate (2016) , actually I didn't see any annoying bickering  

this is hilarious drama

 Unidentifiable:

Encounter 

This is probably one of my favourite dramas for this. They are just so... easy in each other's company. I've seen comments that complain about their supposed lack of chemistry,  but I disagree. It doesn't need to intense - sometimes gentle love is perfect. I found it a very relaxing watch, as I never, ever had to doubt their feelings for each other. They also communicated, which is a massive plus

Oh, yes, I love it too much. Park Bo Gum is so hot with long hairs, the begging in Cuba is so amazing. I will for sure rewatch it. 

(Is there a rule against recommending ongoing dramas? It feels like there should be.)

In Dream Garden the leads haven't gotten together yet but they start out as coworkers, then friends and soon enough there will be romance. The show's editing is silly (to put it kindly) but the main leads chemistry more than make up for it. They are also the reason why I'm on the hunt for more mature romance without too many ups and downs.
