i'm pretty sure its Korean, the scene shows the female lead in a bus, while the male lead is driving a car next to the bus and calling her name or waving, something like that, and the people and also female lead in the bus see him, just wondering what drama has that scene, does anyone know? i've seen the drama but forgot which drama had that scene

 I think Snow white has this scene. http://mydramalist.com/1913-snow-white. It is the second lead though.
Is it Boys Over Flowers? Or something around that time like from 2010 maybe? I think I've seen this before, like it's maybe something that happened a lot in dramas around that time...
Never seen snow white and i think its boys over flowers also
do you have another scene? This kind of scene is in a lot of Dramas
It's not Boys Over Flowers. 
Maybe 'Beautiful Gong Shim'?...
Pinocchio has that scene but it's the second lead that's in the car and I think something about 1percent also has that
I've seen it in Pinocchio. The girl hides behind the guy that rides the bus with her while the other guy drives next to the bus.
The first thing that came in mind was also Pinocchio but it wasn't the male lead

Difficult to say since most of K Dramas has a scene like this.

Is it “Love story in Harvard” ? I think there’s a scene like that there.
