[US Sale] It always pays to be a good neighbour, especially with three beautiful women living next door...
When Mark helps his three female Korean neighbours move into their new apartment, he doesn't think much of it.

First up to show her appreciation is Seo-yun, a spunky emo-chick, who knocks on his door, determined to figure out if Mark is a good or bad neighbour, and willing to go to any lengths to find out.
