49Days is really the only Korean drama you've seen so far? :)
My recommendations:
Delighful Girl Choon Hyang - It's a really nice romance story with lovable, quirky characters; "forced" living situation
Goong - The setting is gorgeous
Full House - One of the "classics"; "forced" living situation
You're Beautiful - Involves gender-bender and idol genre
Personal Taste
Secret Garden
Coffee Prince
(In case you like Jung Il Woo: Flower Boy Ramyun Shop)
My Girlfriend is a Gumiho : it got it all; romance, laughter, fantasy
Secret Garden: One of the greatest K-dramas ever!
You're beautiful : idole/romance/laughter
My girl : so much fun while watching it
Well, you haven't yet watched You're beautiful...Scent of a woman might suit your taste... And I highly recommend kmovies: 100 days with Mr. Arrogant
My Sassy girl
My tutor friend (1&2)
Project Makeover
Seducing Mr. Perfect
He was cool
Temptation of Wolves
Cyrano dating Agency
Some of those are a bit more cheerful but all very good.
Secret Garden all the way. One of the greatest. Rich guy falls for poor girl, and constantly pursues her.
Flower Boy Ramyun Shop is a younger male older female romance. It has to be my favorite.
Coffee Prince if you're wanting something steamy.
The Moon That Embraces The Sun is a historical drama, and it's amazing. One of the greatest heartstring dramas.
You're Beautiful is a cute, quirky drama. This drama is full of that first love innocent romance.
