School of Lock is an ambitious entertainment content by THE BOYZ, who have completed their successful activities with their new song Maverick. The game was composed of a survival format in which the final winner was selected by holding a "Maverick Game" against the backdrop of the school classroom, drawing interest from fans.

The rules of the game will be played by the last remaining member or team winning the key and taking over the prize money in the safe. THE BOYZ, divided into a total of three teams, attached a heart sign indicating survival to their chest and increased the thrill with all their efforts to escape the school after three games: placement, logic art, crying students, and cooperation.

In addition, THE BOYZ members' reasoning and quickness, which show their sense of entertainment as well as their ability to cope with cold situations, doubled their immersion in the remaining episodes to be unveiled, signaling the creation of THE BOYZ's "best" own content.
