recomend me some nice love story with a very novel point

Just finished the drama A Love To Kill.   The male lead taking revenge ON THE FEMALE LEAD (eventhough ut teally isn't her fault) yet ends up falling for her. WARNING : EXTREMELY SAD. But an EXCELLENT drama, a MUST WATCH in fact.

Rain and Shin Min Ah as the leads, VERY good acting, they  did a great job potraying passionate love.

Mega addicting since about ep 4-5, bear with the buildup in the 1st 3 eps
