I feel like I'm slowly understanding parts of chapter 0 now after we finally got to chapter 260-261 because in chapter 0 ryun got petty and quoted "how dose it feel to lose your muha" and talking about how he traveled this far so don't die and offered to help get eunwal back because if I remember correctly his mission is to technically protect/help her so she can complete her mission
