Hello ^^

I'm wondering if there is a drama about a shy boy and a girl being best friends, but the boy secretly loves the girl? 

I have only watched Absolute Boyfriend/Zettai Kareshi/Absolute Darling, but I'm looking for something less science-fictional. xD

Any suggestions? ^^

Thanks in advance!

The only ones that pop into my mind are: Proposal Daisakusen and Good Doctor.
Good luck!
Operation proposal is the only other one I can think of with the best friend element.  It is the Korean version of Proposal Daisakusen that was recommended above.

Operation Proposal
I second Reply 1997 :)


Hoo goo's love is exactly what ur looking for 


I agree with the suggestions of Reply 1997 & In Time With You both are excellent dramas and the premise is exactly what you are looking for 
Definitely In Time With You. 
Also while he's not shy, you might want to watch I Need Romance 2, it has the falling in love with your best friend theme as well. 
You could try the currently airing The Time We Were Not In Love. Its the Korean remake of In Time With You.
Agree with:
- Reply 1977
- Proposal Daisakusen

In addition:
- Nobuta wo Produce (but the romance is not the main story)
- Plus Nine Boys
I recommend these, they're all quite good
