"GENTO" is part of Pagtatag!, the second EP of SB19.

In an interview with the press during the launching of Pagtatag! in June, the group shared the concept behind their latest EP.

"Kung sa PAGSIBOL (previous EP), nag-eexperiment pa kami, sa PAGTATAG, alam na po namin kung sino ang SB19," member Pablo said.

He added: "Makikita niyo po sa mga kwento ng songs na parang, 'Ah, ito 'yung nangyari sa SB19. Ito sila ngayon. Sa PAGSIBOL, may icon po ‘yung album na question mark. Tinanatanong natin kung sino at ano ang SB19. Dito po sa PAGTATAG!, sinasagot na naman ‘yung tanong. Ito si SB19 at ito ang kwento ng SB19."

The group also shared the story behind their hit song “GENTO” off the EP.

"Yung gold, matinding proseso ang dinadaanan. Gaya sa amin, matinding proseso po ‘yung pinagdaanan namin. ‘Yung hard work namin, blood, sweat, and tears ang binuhos namin para makarating kami sa ganitong lugar,” member Ken relayed.
