Did his Uncle really show up? Or was he just hallucinating or having a nightmare about it?

judging by his clothes
yes he was really there

I mean I'm looking back at it now and the blood spots from the cut wound are no longer there, whereas SW had to go through so much effort to clean Bum's blood. There's no evidence of more blood? Also when Bum "wakes up" from the banging on the door, after falling dizzy, his shorts are pulled all the way up, no longer down and exposed like before. Now that I'm seeing it again I think he dreamt/hallucinated his Uncle?
I'm starting to not like this story... Ahjussi is clearly being manipulative. He knows what he's doing. This is just so wrong. I'm so disappointed in Ahjussi.
Right because he even saw his phone that he has plans on that day
Exactly! What the heckie is his problem :/
