A rich girl falls in love with one of her classmates.

She tries all the wrong ways to buy his love, but it never works. She gets pushed back again and again. Really painful to watch, although she is a real rich brat.

Until one day she decides to fall in love with a seemingly "good guy", another one if her school comerades.

On her wedding day she runs away before the ceremony and gets stabbed in an abandonned building.

An angel appears and gives her 7 days to find out who stabbed her and why.

She walks back in her own tracks and finds, that some things she had done had brought bad karma to herself and others.

She also finds out that many of the things she had firmly believed in had been fake.

Resumé: a nicely short Cdrama to watch inbetween. 11 episodes. Nothing lengthy.

Is it a happy ending?
Let's turn it like this: it's a clement merciful ending. Not a conventionally happy one.

I really liked young Rebas acting here. It also sounds as if it was unsubbed by a voice actor. Which worked pretty well.
