They are getting cut.
In the novel, the Ha sees Ji wandering down the hall realises what happened, and brings him to his apartment, makes him feel safe, more present, and sort of does some very basic care to settle him.
He then returns to the centre and nearly kills the other Esper. However in the last chapter they show Ha leaving Ji in the hall only for this chapter that opens with the beating, it implies that Ji is still at the centre only to not be.
It’s a vital part of the story being cut because a big aspect of the novel is how they help each other heal from their past traumas. And Ha shows how he’s able to put aside his wants (of harming the Esper for hurting Ji) and rage aside, to take care of Ji and provide safety and security for him which he needs after the attempted SA.

Is it just me or its hard to make sense of the story, scenes keep getting cut, i feel like one time there is something going on , then in next chapter something completely different is happening. I am getting very confused. The story isnt flowing well. I also get confused btw their dialogues. I dont understand who is saying what…
