This is especially true for Yu Lim, who easily qualifies as one of the most unlikable protagonists in a Korean romance ever.
Yu Lim decides to pursue Choi Hung, not using pure charm, but through a variety of questionable means, including his power of authority (he forces her to socialize with the other teachers outside of class), endless sexual banter, and even nearly raping her in a mutual moment of weakness. One of the best decisions director/co-screenwriter Han Jae Rim makes is to not create charming and likable characters.While some think that they should go hand in hand, it seems that the characters in Rules Of Dating see these things as apples and oranges.The result is a sexy, mature, and unconventional romance that may be too challenging for some. Rules Of Dating (or known in the subtitles as To Do Or Not To Do) stars Kang Hye Jung (Old Boy) and Park Hae Il (Memories of Murder) as high school student teacher Choi Hung and her counselor Yu Lim.Review: Another movie that doesn't meet the expecations the cover and title raise. "Rules of Dating" was most likely promoted as a comedy romance out of marketing reasons.In fact director Han Jae-rim's debut is a romance drama that tells a good story with extraordinary characters.
