Overall story for this drama is really adorable and sweet. You never get to be bored anywhere also Lee Seung Gi was awesome in this drama with his hilarious acting. I loved his interactions with his grandfather who himself was really hilarious. Shin Min Ah was super adorable. I really loved her because of her innocent nature and love for almost everyone. Director Ban and Min Sook were love. They were seriously meant for each other and I loved them act like clumsy teenagers!!! Now coming to my favorite Teacher Dong Jo. He was sooooo cool and only normal person on the show kekeke who unfortunately fell for Gumiho. His part is super sad, I wished he would have ended up with someone cool or just ANYONE because I do not like the idea of his being alone for another thousands of years TT-TT Acting was so cute, funny and really good overall but for me Director Ban and Min Sook were best when it came to acting =p Music was soooooooooo good. Especially 'Trap by No Minwoo' and its instrumental. I was goner for this one. Other OSTs were really lovely too =3 Rewatch value is 5 for all those scenes between Gumiho and Dae Wong because they were adorable together and funny too. A perfect comedic and romantic couple =3 Overall I gave 7.5 points just because I was super heartbroken because of Dong Joo and because the ending was a bit clumsy.
