I just finished watching the series Heartstrings. I absolutely loved the chemistry between Park Shin Hye and Jung Yong Hwa. All of the songs were great, and the series was full of entertainment. Almost all the actors and actresses delivered great performances. I really enjoyed it. Park Shin Hye and Jung Yong Hwa had acted together before in the drama You're Beautiful. Although they weren't a couple in that series, I still wanted them to end up together. So, I was thrilled and excited while watching Heartstrings.
