I would recommend to wath the first taiwanese version: It started with a kiss and the sequel They Kiss again. This version has two seasons, which followed the whole story from their high school years till their working years. Ariel Lindoes a pretty good job with her character, making you empathize with her splendidly.Joe Cheng perfectly fits the cold, genius character. He does it so well that sometimes you really want to smack some sense into him. Many loved Ariel and Joe’s drama couple, and they even made other dramas together due to people wishing to see them together again. And also the Japanese version Itazura na Kiss - Love in Tokyo. With two seasons and one special, this remake was way better than the original version. Like the Taiwanese version, it followed the complete story. This version is a little lighter than the Taiwanese version and there aren’t as many crying scenes for the leading lady.
