Highly likely, yea. It would be some sort of continuation from the kill of Jieun. In ch19, I think Sangwoo wanted Bum to feel relief from killing like he did. Sangwoo didn't get the response he wanted from Bum in the start of the first season. So perhaps killing someone who Bum hates might change Bum's thoughts about killing.
Yeah, I also think that Sangwoo was trying to agitate Bum. Like with the meat thing and then him cutting specifically red cake. Sang woo killed someone so he has to know.
Really? I think Sangwoo was really just asking what he wanted to eat. And might have only realized the effect of his words afterwards. Lol but yea, perhaps Sangwoo did have a motive behind the meat thing, he's quite a little shit after all lol
Sangwoo is probably going to make Bum kill the uncle...saying he should for the way he treated him. Its probably going to bring Sangwoo back to his abuse and how he killed his parents.
