Cute/Puppy or Charming Male Lead

School 2017 

Definitely:

• I Need Romance 3 - the ML can be charming and also puppy like, but is mostly just super sweet
• Coffee Prince - it's older, but it's right up there with Healer, WFKBJ, and Fight for My Way in terms of affection and chemistry between the leads
• Live Up to Your Name - the actor did a great job of portraying a ML that was mostly pretty goofy, but could also be a talented and professional doctor when needed and very serious in moments that called for it; once the leads warm up to each other they have lots of fluffy moments and good skinship
• Bromance - extremely fluffy; the plot is an excuse to put the leads through every great romance trope in the book 
• Splash Splash LOVE - short, light, and fluffy
• Queen In Hyun's Man - the ML is very smart but happily wasn't put into the "cold genius" box, he's both puppy like and sweet, and very capable 

Worth trying:

• Love in the Moonlight / Moonlight Drawn by Clouds - the ML starts out a little bit rude and pompous (its pretty light hearted teasing, and the FL matches him right back), but very quickly becomes friends with and then falls for the FL
• Eternal Love - in the very beginning the ML is a little bit cold and rude because he suspects that she is spying on him (and he's sort of right), but as soon as he becomes interested his questions are more playful than really suspicious, and later on he's only charming and sweet; a good amount of fluff and skinship
• In Time With You - the ML is the FL's best friend. He's the opposite of cold and rude. The only reason I'm not putting it in the "definitely" list above is that the drama does require some patience. I am not a patient viewer, so the waiting was painful for me, but I was glad I watched it because of the payoff in the end. 
• Love O2O - not a puppy, but certainly charming and never aggressive or rude + very fluffy
• The Princess Wei Young - charming, good team work
• W Two Worlds - ML is charming, and once he decides to be romantic, he shows that he can also be very cute / sweet. A mix of action and fluff. 
• Because This is My First Life - not a puppy and not exactly "charming" per se, and in some ways he might seem a little cold or even rude, but really the ML is very sweet and thoughtful in his own way and he has a certain... charisma? This drama has a quiet feel to it, but I was never bored. 
• Something About 1% - the ML does start out as rude and a demanding boss (although nowhere near as bad as some of the typical rude tsundere drama MLs I've seen) but quickly softens up / shows his softer side; I include this one even though on paper he's the kind of ML you're looking to avoid because I found it a refreshingly different take on this type of character, the leads had great chemistry, and there's lots of fluff.
• Sound of the Desert - he's forward in his pursuit of the FL, but I wouldn't quite call it aggressive, especially since she's perfectly capable of matching him. Lots of fluff and also steaminess later on. 
• Hi! School - Love On - the plot and writing are a bit basic, but the leads are super cute
• Bring It On Ghost - basic, light, fluffy
• Witch's Romance

Witch's Romance, Ex-girlfriend Club, Bubblegum, Discovery of Love, 20th Century Boy and Girl.

  • While you were sleeping
  • Live up to your name
  • 20th century boy and girl
  • Can you hear my heart
  • Kill me heal me
  • That Fool

I didn't mention this one because of the lead didn't fit but you're right I watched this one and I LOOOOVED it so much! I loved this type of male lead because I think he did it well and it was really fluffy with great chemistry ^^

 AH:

Coffee Prince - it's older, but it's right up there with Healer, WFKBJ, and Fight for My Way in terms of affection and chemistry between the leads.

I actually didn't like Coffee Prince because the story itself felt too slow to me, BUT I WILL TRY EVERYTHING ELSE YOU MENTIONED ON THE LIST thank you sooo much for the long list of recommendations <3 <3 <3

I'll admit I ended up skipping almost all of the scenes with the SL when I watched Coffee Prince. 

You're welcome! I hope you find some other dramas you like in the list!
