Dramas where the ML is intimidating but slightly flirty too?

Hi! I've been watching kdramas for a while but just recently got into cdramas. I'm looking for a specific type of vibe where the ML is mostly serious/intimidating, but looks at the FL like she's his whole world, but also has some playful/witty banter with her.

Wuxia/xianxia recs are fine, not a huge fan of body swaps or time travel/resets but if they're done amazingly then sure. Happy ending preferred, or at least a reasonably rational one (The Double ending was completely unnecessary hot trash) - btw I don't fast-forward and don't skip endings unless I actually drop something entirely.

Perfect examples:

  • You Are My Glory (already watched it 3x in 1 month lol, love their little pranks)
  • The Double (just finished and can't get over Duke Su and his little smirk)

Ok examples:

  • Amidst a Snowstorm of Love and Love Like the Galaxy (not much teasing/flirting)
  • Who Rules the World (fits on paper I think? but I didn't get the same feels)

Watched/watching:

  • Destined (just started, seems good but not the same vibe)
  • Fireworks of My Heart (liked for Yang Yang's angstily pining face)
  • Go Ahead (liked but not for the romance)
  • Love O2O (didn't like - no chemistry and YY spoke like a robot)
  • The King's Avatar (liked but the plot armor was ridic)
  • You Are My Hero (liked)

Also I really want to watch Story of Kunning Palace, but am waiting until I have a month to spend binging iQiyi - feel free to still rec other iQiyi dramas though and I'll queue them up! Otherwise I have Netflix and Amazon US, Viki, and whatever's on Youtube. Thanks! =D
