Su-ho (Cha Tae Hyun), a simple teenager, and Su-eun (Song Hye Gyo), a pretty and popular girl, start dating. Their love is for each other seems eternal. By leaving messages to each other on the phone, and through their many times together, their love grows stronger. Until a tragic event occurs.
This is the Korean remake of the Japanese movie, Crying out Love, in the Center of the World. Try not to compare both movies, for I think each movie has it's own "oomph", so just a tip, so you wouldn't ruin it for yourself. Oh, and Song Hye Gyo in the movie!...weee!
