I am well aware that Fated To Love You may not be everyone's cup of tea, but it is one of my favourite KDrama, the first one I ever watched and probably the one I'm most attached to.
I already watched it twice and, upon second viewing, I was surprised to find many, many funny moments I didn't remember at first.
It can be a be a bit (voluntarily) over the top sometimes, but the truth is that this show has many qualities: a solid plot, amazing acting, two perfect leads (Jang Hyuk and Jang Nara have an incredible chemistry) and comedy and drama are very well balanced.
Last but not least, the score is beautiful, especially "Destino"... it breaks my heart.
