I’m still thinking about the final monologue, where Yang-il-woo mentions that he should have killed Gyeom if he had known what Gyeom was going to do to Bek-hee. I think this refers to the abuse and manipulation that were likely recorded on his phone—recordings he can’t listen to now because the device is damaged—and it’s highly probable that Gyeom is going to beat Bek-hee so severely that he might leave him in critical condition.
