heartstring is a lovely drama.it has awesome music and is one of my most favourite drama.i am a big fan of romance and it is shown really well in this drama. its quite different from those love triangles we normally see. after watching this show , the main guy lee shin has become my ideal man! and i like park shin hye character here more than in your beautiful. she sure has good acting skills!! if you really like love and romance including awesome music , this is something you must watch!! i liked the way they slowly fell in love. i think my best episodes start from ep 7 onwards. since this is my most fav drama i have no complains!! it is a MUST WATCH drama
