Why did Sun-Ae hate Kyungh-Ah ? (spoilers maybe)
Just watched this excellent little ghost/slasher movie. The story however left a few holes (maybe the translation was not always 100% accurate ?). Sun-Ae says as an explanation for her hatred of Eun-Ju (Kyungh-Ah), that she simply didn't like her. That seems a bit thin, and throughout the flashbacks we see that Sun-Ae usually acts hostile whenever Kyungh-Ah gets together with Hye-Jin.
At the exposition we kinda find out that Kyungh-Ah has feelings for Hye-Jin (which was alluded to in the flashbacks as well), so maybe Sun-Ae was jealous of her affections ? But then, one flashback said that Sun-Ae was in love with the baseball player. That still works though, as the baseball player falls for Eun-Ju as well. So maybe two of Sun-Ae's "love" ineterests are captured by a rival ? Makes sense ?
What are your thoughts ?
