Looking for a novel

Hi, I'm looking for a novel I've read a few years back.Here's what I can remember of the story :
I think it is a chinese or korean novel (not certain)
Might have been adapted in a manga, but then again, I'm not certain.

The protagonist is male.
He is playing a mmorpg. Most of the story happen in the game.
Protagonist start as a healer but later become a swordman or warrior. He keep one of his healing skill though.
I think he is a college/university student.
The was a really pretty girl.

The story wasn't finished when I read it, sorry I cant give you more details.
Thank you
