k-drama romance with healthy relationship

I don't typically love C-dramas, they have too much filler.  Though I fast forwarded through all the gaming and space stuff, I LOVED the romance between the main characters.

I would love to find a K-drama with the following (do they even exist?):

Good romance, healthy relationship

Non-rushed happy ending

Spend more time together than apart 

No ridiculous misunderstandings or breakups

No evil exes or parents trying to keep them apart

Good chemistry (no open-eyed fish kisses)
No historicals or BL

Low angst

Any recommendations you could make would be greatly appreciated!

Five Children - family drama, multiple couples

Thank you for the recommendations.  I've seen the ones suggested, other than Five Children and Homemade Love Story, and since I have the attention span of Dori, I'm not going to give them a try.  I tend to get a little twitchy if I see that there are more than 12 episodes to watch.

I loved Once Upon a Small Town!
