Any other Male Lead similar to the one in The Bride of Habaek?

 YeojaChingu:

Any dramas with a serious, non-clingy, arrogant, but compassionate male lead? I hate it when the guy shows off his love to the female too much, it is boring. My favorite guy ever has to be Habaek, and Irie Naoki from Mischievous Kiss (Itazura na Kiss) but are there any others? I prefer Korean dramas, but could be Japanese too. 

Based on this criteria, you might like these Korean dramas:

• Sungkyunkwan Scandal
• A Poem a Day
• 100 Days My Prince
• Hello Monster
• W Two Worlds
• Mad Dog (the romance is not the main focus of the drama and is a total tease)
• My ID is Gangnam Beauty
• Because This is My First Life
• The Master's Sun

Chinese and Taiwanese dramas that also fit your criteria well:

• A Love So Beautiful
• Love O2O
• Go Go Squid!
• Attention, Love!

Princess Agent - Cdrama. I also recommend you this.
