A meaningful gift box
A father giving his daughter a birthday present in Squid Game appears completely innocent, but everything seems to have a secret significance.
The black gift box with the lovely ribbon foreshadows what’s coming up in the games, not just in terms of coffins but also in the violence the participants will encounter. You may recall that the present inside was a weapon-shaped lighter, which alludes to how losers of the tournament are “eliminated” and then cremated.
