I watched because of Park Shin Hye, not so much of Yong Hwa. He is good looking but his acting skill is a bit low rate. Even in You are Beautiful, he was only so so in his role, luckily Shin role is supposed to be cool and reserved. But in Heartstring, he need to be more emotional, playful and a little arrogant character. He cant bring that out. Poor PSH,no doubt she is good but her main lead spoilt it for her. Sad to say, I will rate it ordinary, as I actually skip to watch the final just for the sake of finishing the whole episode. Its a total bored drama.
