I don’t think the person in the first panel who is biting into the apple is Yoobum. It is defiantly Sangwoo’s mom. Sure they have the same clothing but the hair is not bum’s also bum doesn’t have a mole on his chin but the mom does. Bum also has bandages on his face that are not there in that scene and his red bucket hat is gone. I think that since Sangwoo is talking about the time he was eating apples with him mom he is imagining his mom as bum which he has done before. Also when he is telling the story and in the next panel talks about how his mom tells him to try an apple and the panel implies that Yoobum is handing him an apple like Sangwoo’s mom would have done but then in the next panel you see Sangwoo reaching into the bag and getting an apple. It’s clear that Yoobum never tried to hand him an apple. Thoughts?
