K-drama recommendation please?

Dear friends, could you please recommend a good Korean drama to watch?
I will be very specific about what I like:
1. Only Korean drama, please
2. Only with HAPPY ENDING - no dying or killing in the end
3. VERY VERY ROMANTIC

Now, I want to list some of the dramas I really enjoyed:
1. Personal Taste (Lee Min Ho)
2. Attic Cat (loved their relationship)
3. Dal Ja's Spring (loved their relationship)
4. 1% of everything (loved their relationship)
5. Pasta (kept my interest high)
6. Full house (Bi - rain)
7. Prosecutor Princess (kept my interest high)
8. The Snow Queen (interesting plot, even though the ending was sad)
9. Witch Yoo Hee (interesting plot, great romance)
10. Sungkyunkwan Scandal (interesting plot)
11. Last Scandal (great romance)
12. City Hunter (Lee Min Ho)

Here are some dramas I did not like (please do not get upset if you
like them - we all have different tastes)
1. The Greatest Love (did not like their relationship)
2. Boys over Flowers (too much about the school)
3. Mischievous Kiss (not enough romance for me)
4. The God of Study (too much about the school)
5. 49 days (do not like magic)
6. Dream High (not enough romance)
7. My girlfriend is a Gumiho (do not like magic)
8. Secret Garden (do not like magic)
9. Lie to me (did not like the actress)
10. Baby-faced beauty (did not like the actress)

As you can see, I have already watched quite a few :) So this is why I
am asking for your recommendations. I will be forever thankful!

THANK YOU VERY VERY MUCH. Kamsahamnida. Sarang-he!!!
