As i call it "The ONLY drama that made me cry rivers" for endless times. Just in case someday i got Alzheimer i want people to make me watch this drama for it has covered a big part of my life. well to begin with reading the reviews here i respect all opinions but why people are bored with a slow flow !! they gave u details on how they TRULY fell in love how he met the friend ... hwo he lost her .. how he found her again .. how heart braking it was ... u gotta be patient for such great flow of details, u gotta love the idea that u actually feel that u grew older with them... i believe this has been one of the best slow dramas i've seen ever. My N°1 drama more than 10 years and i'm still hooked way too hard. everything every lil tiny detail about this drama is perfect , the story , the acting , the songs ...... absolutely everything is perfect. the story sure is amazing ... one of the best stories in k-land ... it is a full package .. LOVE , LOYALTY , FRIENDSHIP, BROMANCE... even if u r new to the drama land .. u must check this mater piece *-* u shall not be disappointed , u will love it and cry rivers because of it.
