RBD-309 - Female boss, until she falls... Misaki Shiraishi

The lead actress is fantastic. Instead of just screaming, she moans and tries to hold it in, which really builds the tension. (Screaming like it's cheap just kills the mood and shows a lack of acting skill.) The disappointing part is the actress playing the aunt—she has a square jaw, an unappealing face, and no sex appeal. Plus, the scenes after she appears aren't particularly interesting either.
