how did baek jin die in weak hero

Baek Jin in "Weak Hero Class 2" dies off-screen, with his death revealed in the post-credits scene of the final episode. Although the exact cause of his death is not directly shown, it is strongly implied that he was killed by Choi Chang-hee (CEO Choi), the ruthless gangster leader he worked under. This likely happened because Baek Jin failed to control the Eunjang High students and lost a critical battle, disappointing Choi. Baek Jin's funeral is attended by his former friends and foes, and the post-credits scene reveals the leadership of the Union is up for grabs after his death. The show leaves some ambiguity around the details, but the consensus points to an orchestrated killing by Choi as punishment for Baek Jin's failures.
