@Utaku: we need your hint to keep going!
Maybe a gentleman's dignity?

Guys let's continue until she / he comes back ^^


Pretty easy:
Hint:     It's a korean drama
Hint 2:  One lead loves chicken and beer (I basically gave it away with this ^^)

Hint 3 in white Colour for the people who don't get it with these two hints ^ (mark it with your cursor and you'll see it:

Hint 3: The male lead has lived on the earth for a long, long time because he can't return to his home
You who came from the stars? 

I've honestly never finished that drama, and it's been quite some time ago. Not really sure if a lead loved chicken and beer. But its a guess based on your third hint. 
Focussen you're right ^^
O yeah! I really should re-watch that one again, and finish it. 
Anyhow.. 

Hint 1: One lead is a plastic surgeon. 
Hint 2: The other lead is a general. 



Neylana  it's your turn give us something hard ^^" 
OOOh sorry guys! HMMMM
tip 1: It's a non-love marriage (at first ^^)
tip 2: The actor is a singer (not in the drama though)

easiest tip (only look at it if you're desperate) (it's in white font, so mark it with your mouse)

It's a doppelganger drama (2 personnages look exactly the same - played by one actor) 
Bride of the Century?
Wsa67 you got it right! Now it's your turn ^^

Hint #1: Male lead is single father
Hint #2: Male lead falls in love with blind woman
