What happened to Joon Ho Squid Game?

Jun-ho was shot in the shoulder (before falling off a cliff into water). So he might not be dead, though he doesn’t seem to have ratted out the game masterminds to his fellow cops, since the game is continuing.

Hwang In-ho (황인호 Hwang In-ho?) also known as the Front Man, (프론트 맨 Puelonteu Maen?), is the current head staff member and the person who oversees the Squid Games . He is the brother of Hwang Jun-ho, and became the Front Man after playing and winning the 28th Squid Game in 2015 (as Number 132).

Gi-hun returns to Sang-woo to inform him of his decision, but the latter stabs himself in the neck – presumably a consequence of his guilt. Sang-woo’s last words request that Gi-hun accepts the prize money and helps his mother.
