Film yang Rilis April 2008 ini temanya drama cinta bgt heu... Tapi bagi gw lumayan bagus... Walaupun Love Triangle termasuk paling sering ada di film, tapi untuk film ini agak beda... Cuman akhir2 film alurnya cepet banget, dan kerasa kurang, awal ampe 3/4 film menarik banget... Untuk pemaen utamanya dah lumayan sering liat, ada Jang Geun-suk nu maen di Hong Gil Dong ama Hwang Jini, dan ada Cha Ye-ryeon yang maen di Bad Love...
