* The scene in which it is [[TheReveal revealed that]] [[spoiler:Su-yeon is actually dead]]. Moo-hyeon's agonised tone of voice when yelling the truth to Su-mi, the latter's stunned and horrified reaction, and Su-yeon's horrified, broken screams [[spoiler: as she slowly backs away from her sister, the latter desperately reaching out to her with a "no, no, this ''can't'' be true" expression on her face.]]
* The ending flashback sequence. [[spoiler:Su-yeon is left to die, broken and helpless, with the corpse of her mother for company.]] There's also the very last shot of the film - [[spoiler:Su-mi wanders off into the woods, by herself, but not before taking a glance back at the house, as if she knows something has happened but can't quite imagine what, and the audience ''knows'' what's going to come next for the poor girl.]]
* Moo-hyeon's entire situation. [[spoiler:He lost his wife and his youngest daughter ''on the same day'', and his oldest daughter absolutely hates him for having an affair (or so she believes, as it's [[MindScrew never made entirely clear if he and Eun-ju were ever in a relationship in the first place]]), and he can never get through to her despite his best efforts.]]
* The very last shot of the film, which the ending credits start to play over. [[spoiler: It's the scene at the pier, [[OnceMoreWithClarity except this time]] Su-mi is sitting by herself.]]
