This is  a perfect show - great acting,amazing chemistry, perfect casting, good music and well plotted story. Nothin seems unneccesary,  it all leads to something.
I watched it a year back and watched it now, brilliant...anyone loving asian dramas or romantic dramas in general, watch it. Fresh content, well written.
The main leads acted so well and that kid was so cute. The relation built between the grandma and grandson was so well done.
You do get angry with the heroine for not grabbing happiness but u thn realise that is her character trait that they have maintained throughout.
Worth a 100 rewatches...best drama ever!
