I'm really shocked to see that some gave it one or two stars... Guys who gave up on it please watch the rest. I actually started to watch this series because of nam joo hyuk.. but actually fell in love with female lead. She may be loud annoying or anything but I can feel her pain and it reminds me of my school life. I can't think of other actress for Na Hee Do.. I strongly recommend twenty-five twenty-one to all kdrama lovers ❤️
