This movie was so full of emotion! Starts out giving a look at the life the protagonist Kim Go Eun lives with "Mother" - the boss of a loan shark business played exceptionally well by Kim Hye Soo. There are many other children in the company but there are only four children who live with Mother in the same house. Two boys, and two girls. One of the girl is a junkie, and Kim Go Eun becomes like mother when she grows up, and all the kids are tough but Kim Go Euns character has been living such a life and even seems to be used to it when suddenly mother sends her on an errand to collect from a man. But when the girl goes to the apartment she finds Park Bo Gum living there and he tells her politely his father isn't a bad person, he will pay off the debt and asks for some time. She realizes that he's a good guy so tries to tell him his father has abandoned him but he won't believe it. She gives him some time but then she starts having feelings toward Bo Gum and he seems to like her as well. Anyway that's when everything goes to shit. This movie was a bit like Hwayi, at the core it was about dysfunctional families and how you get trapped by the idea of a family even if it literally murders your happiness. This is very serious extreme kind of violence so if you get triggered easy might want to pass on this one but otherwise this movie is super intense and beautiful.
