This is one of the very first romantic comedies I watched early on when my KD addiction started. I must say that any rom-com I watched after just doesn't compare. Lee Sung-kyung was amazing, she was very believable as Kim Book-joo - a daughter, a girlfriend, a friend, a student, a roommate, and of course, a weigh lifter. The development of the romantic relationship between KBJ and Jung Joon Hyung was phased right, not too slow nor was it too fast. There are so many sweet and memorable moments with them. The chemistry if the entire cast is magnificent and it's evident that they like working each other.

I could watch this series over and over again and it will always be worth my time.
