Fluffy and light-hearted romantic comedy dramas like Touch Your Heart?

I watched Touch Your Heart a couple of weeks ago and can't let go of it. I'm basically in love with how easy and fluffy everything was. I love how there's little conflict and the drama that arose was settled immediately. It was just one of those dramas that made me really happy while watching it. Despite that, it was also very mature in some cases. The romance between the male and female leads was so sweet and so healthy unlike some other romantic dramas we see.  It was just a joy watching the two leads fall in love and overcome hardships together. So, I'm looking for something similar with the following criteria:

- Fluffy romance

- Office setting, or basically anywhere that is not a school

- The male and female leads get together fairly quickly

- Aloof/colder male lead, cheerful/sweet female lead

- Funny moments (Touch Your Heart made me laugh aloud with so many of its scenes)

Thanks!

Her Private Life (2019)

Jugglers (2017)

What's Wrong with Secretary Kim (2018)  

Boss & Me (2014) (c-drama)

Suspicious Partner (2017) (it has a bit of suspense & crime but it's has many fluffy moments)

Thanks for the suggestions! I watched all of these but Jugglers, so I'll be checking that out. 

In addition to the ones other people have mentioned, maybe try Boss and Me.

I've actually seen Boss & Me! Good show!

Oh, also A Girl and Three Sweethearts, they don't get together quickly, but it's sweet throughout.

20th Century Boy and Girl (the male lead isn't aloof/cold though....I'm also not sure when they got together either but it's a cute romance and the characters are likable)

Intense Love (I wouldn't really say this is mature...it's kind of a drama you watch if you just want a fluffy romance. The male lead is aloof though not mean. The female lead is a celebrity, and she initiates the romantic scenes a lot. They get together quite quickly, and there are comedic elements. Misunderstandings happen, but when they do, they don't drag it out and acknowledge what they did wrong). Some people didn't care for the secondary characters though.
