IDK if you wanted a real answer but lol here you go. I think it actually may be real, but not 100% sure. In Ch 29, Yeonduk had a coffee can in that box, so it may be the same coffee can from the extra. But the reason why im not 100% is the two cans look different (the labels) but like i may just be looking into it too much (TДT) ijustwanteveryonetobehappy
OH NOOOO YOU'RE RIGHT. I just wonder because, the author originally had a different version of this story released and then re-released. i won't deny this happened but it feels a bit out of place/ disjointed from the series so I feel like it was taken from the original storyboard for the can he has in the box and they had already slightly altered skyler - but yeah it's not like it's so out of place that i don't believe this happened in the past. seems douche-y and unreasonable though that skyler was happy about a present from someone he thinks isn't his friend/ is his enemy and seems to enjoy having him as a slave-friend - seems more douchebag than him thinking yeongduk hates him and ignoring him / treating him like trash
if that extra was the real story i would cry. WAIT IS THAT REAL GUYS? I DON'T NEED THIS RIGHT NOW. IDC IF IT'S IN THE PAST NONONO.
