You Are My Spring.
To be warned there's a killer element in there.

Splash Splash Love.

I would go old which means you have probably seen it already but Hospital Playlist and Reply 1988 would be my top recommendations. Twentieth century boy and girl, Let’s eat 2 or 3, Would you like a cup of coffee, The Best hit. They all have various levels of angst at some point whether it’s second lead or noble idiocy but the general vibe was feel good for me.

1. A Business Proposal (not perfect but I still think it fits your bill overall)
2. Sh**ting Stars (with some strange minor arcs)
3. Live Up to Your Name (but the way they travel through time might be triggering for some)
4. When the Weather is Fine (the overall vibe)
5 Descendant of the Sun (but I watched this one a longggg time ago)
6. I am not a Robot
7. Dali and the Cocky Prince
8. Healer
9. Hometown Cha*3 (involves a trauma)
10. StartUp (highly recommended because Baby Kim Seon-go starred in it)

I’ll tell you more if I remember more. I have to go check my show page.

The Answer Me series (Answer Me 1988 is my favourite)

The Package

Racket Boys (tho it does deal with some sport abuse however it’s a minor story arc)

Let’s Eat Series

Any Park Hye-ryun works, Pinocchio is my personal favourite

There is a whole lot more, but I’ll leave that to other beanies

I feel like there aren't too many purely feel-good k-dramas nowadays. Gotta have a stalker/serial killer somewhere in there 😅. Since there've already been a lot of k-drama recs, I'll recommend some other Asian dramas -

C-dramas
You Are My Glory - starts off slow and there may be more gaming scenes than strictly necessary but it's one of the sweetest, most non-problematic love stories I've seen.
The Day of Becoming You - body-swap shenanigans in a hilarious rom-com.

J-dramas
Kieta Hatsukoi (Vanishing My First Love) - Short and sweet high-school romance.
Old Fashion Cupcake - Equally short and sweet romance but in the workplace this time!

I loved Once Upon a Small Town, which was relatively drama-free and light and fun. Short episodes, so I imagine it would be quite binge-able and no serial killers, terminal illnesses, or anything else surprising.

Never Give Up is also on the top of the feel-good list for me. Bromance! Community building! Found family! Married people working out their issues! Figuring out how to be a supportive parent! Loan shark with a heart of gold! My heart was so warmed by the end and I wanted to move to their neighborhood immediately and eat my body weight in fried chicken.

Does it have to be a drama? If not, I highly recommend Baby Singer which aired earlier this year. It was a true delight from start to finish and is easily binged with just 10 episodes. I watched it when it was airing weekly and it was a wonderful, refreshing little break between heavier dramas.

C-drama - New Life Begins
Don't fret with having loads of characters on the screen, the story is light and fast-paced, palace problem at bare minimum and also prepare for food as you might go hungry while binge watching it.

K-drama
Miss Korea - Quite old, same era as You Who came to the stars, but an underrated gem.

From my vast list of dramas I would recommend:
- Fight for my way
- Flower boy next door
- Weightlifting fairy Kim Bok Ju
- Still 17
- Run on
- Our beloved summer
These get rewatched the most from time to time when I need a happy or good vibe booster.

I am going to define a simple feel good drama as a drama that has no stalkers, serial killers, murders, blood, guns, knives, stabbing, terminal illnesses/nearly terminal illnesses, abusive/traumatic childhoods, fights over controlling stock shares, overly nasty in-laws/in-laws to be, overly nasty jilted lovers, revenge themes, bad/abusive marriages/relationships. A feel good drama should have a simple happy ending where everyone gets to be happy (a happy ending to me is not an ending where everyone else suffers/dies so that the happy couple can be together). Then, as I was making my list, I realized that almost all of my feel good dramas had love triangles, and I had to delete almost all of the dramas on the list as love triangles can be stressful since someone is inevitably hurt. So, this is all that is left of my list:

Welcome to Waikiki 1 and 2 Both of very funny and light.
High End Crush Just a fun drama for laughs and love

"Fight My Way" just made me feel good from start to finish. Best friends-to-lovers drama ever.

I would start with BUSINESS PROPOSAL, not just because it is witty but because of its genuinely playful approach to romance.

Then I would add PEGASUS MARKET- a comedy which had some wonderfully poignant moments as we see people who had no hope suddenly get a second chance- and make the most and the best of it- and a man discovers what is really important in life.

WOULD YOU LIKE A CUP OF COFFEE is truly heartwarming- and so few shows are these days.

SPLASH SPLASH LOVE should also be included in any list of feel good shows if for no other reason than that it is fun.

Secret Royal Inspector and Joyi

A recent one, Fanletter Please.
It’s the closest drama to a typical Hollywood Christmas movie, but without the annoying Christmass theme.
No real angst, the noble idiocy is bearable, the compulsary trauma’s not that bad, and the cast look like they had loads of fun.
Ah, and only 4 episodes !!!!

Father Is Strange (as long as simple doesn't mean short, I don't know if this is bingeable by year end)

Chief Kim! Feels good to fight your enemies and bad corporate stooges by annoying them to death!

I second Welcome to Waikiki - sometimes i just turn on a random episode to play while I'm doing stuff. Like watching an episode of the Friends sitcom - you don't really need to know much about the previous episodes to enjoy it.

All great recommendations. It’s difficult to think of a recent feel good drama. I would add 1% of Something or Something About 1%. It’s been awhile, but I don’t remember there being any deaths.

One Fine Week — 10 episodes of 10-15 minutes each: a member of a K-pop girl group is nervous about making. an appearance on a variety show when she comes across her doppelgänger working as a barista. They switch live for a week: hilarity and romance ensue. (And the music is good too!)

Of the recent ones I watched.
Jdrama- Love Mix up. Cute and plenty of feel good. Also, Old fashioned cup cake.
Cdrama- You are my glory. A romcom and enjoyed a lot this year. Leads had great chemistry.
Kdrama- I always prefer the short dramas for this. You drive me crazy, if we were a season.

I'd reluctantly recommend Mystic Pop Up Bar. Reluctantly because there are many deaths and grudges held, but that's part of the story as our heroine has the task to resolve them and she does so in hilarious ways. And (spoiler warning) it has a happy ending, just so you know in advance. There are only 12 episodes (sadly, I'd have loved to watch more), full of good food (! Yes, that too!) and shenanigans in our world, the dream world and the afterlife with a great trio of main protagonists. I have watched it many times already when I needed that simple feel goid drama.

1. Avengers Social Club
2. Rookie Historian Goo Hae Ryung
3. The Secret Life Of My Secretary
4. Hello Me!
5. Semantic Error
6. She Makes My Heart Flutter

I would like to recommend Hello, Me!. Choi Kang-hee plays a woman in her thirties who has lost her self-confidence and zeal for life following a traumatic accident in her adolescence. She relearns how to love herself and starts anew with the help of her brilliant teenage self (Lee Re) who has somehow time-traveled to her timeline, and a potential love interest/supporter. What I liked about the drama is that it does deliver its healing premise, it focuses entirely on the heroine's growth, and the time traveling element meshes well with the idea of getting in touch with your former glowing self and consoling them, and living life for yourself. It also has a hopeful message that while it might be too late to chase your teenage aspirations, it doesn't mean you can set new goals which resonate with your present self, and you might find a new interest or area in which you'd shine :)

Touch Your Heart, I'm Not a Robot, A Business Proposal, and Hometown Cha Cha Cha

The Fabulous was super light and easy to watch.

My roommate is a Gumiho
Shooting Stars
Romance is a bonus book
The secret life of my secretary
Her private life

So many great suggestions! Two that I’d add:

- Go Ho’s Starry Night: 20 20 minute episodes, set at an ad agency. The two leads have great chemistry and it’s fast paced and cute. Some nice cameos as well! On Viki.

- Failing in Love: 10 25 minute episodes about a high school group of friends. Really visually pleasing and interesting. On Kocowa.

Because This Life Is My First: no serial killers, noble idiocy, terminal illnesses, or tragic pasts—just normal people going through the normal ups and downs of relationships. Some melancholy moments, but pretty much a happy ending for all three couples.

Move to Heaven: despite the main characters involvement with the lives of deceased persons, I found this show pretty uplifting.

Haven’t watched these in a while, but I think they qualify:
Protect the Boss
Queen of the Office
A Witch’s Romance
