Why is this so rushed???

Omg they cut so much stuff from the novel, this is like one third of what actually happened in the og story. I mean the novel was frustrating and dragging to the point I wanted to throw my phone out of the window but I feel like they left so much important information out. I just finished the raws and they cut the whole arc about Hyoseop’s backstory (which was extremely traumatic and sad btw, but it really gave his character more depth) also Haechang was so much worse in the novel, he was straight up puppet mastering, scheming and controlling Hyoseop.
