Rules of Dating (2005)

A well-meaning student teacher and an older colleague navigate the slippery slope of workplace romance in the South Korean romantic comedy Rules of Dating (2005). Hye-jeong Kang stars as Choi Hong, an aspiring teacher who’s involved with a young man she hopes to marry. But when an older teacher propositions her in a very forward manner, Choi Hong finds herself unexpectedly tempted. Really the only rule you need to know is that the more opportunities Kang has to strip to her skivvies, the better. The rising star lowers her inhibitions during dalliances with the rivaling Romeos.
