A'tin is the self-proclaimed, small, but dedicated, fandom behind P-Pop supergroup, SB19. The name A'tin is a collective noun (meaning it's never written A'tins) that comes from the Filipino words atin, meaning "ours." SB19 chose the name for their fandom because they dedicate every win and every achievement to their fans and share all their goals, dreams, and victories equally with them. SB19 shares a close bond with its fans, often choosing to interact with them on Twitter, various live stream services, and even in public places regularly.

FUN FACT: Unlike the Filipino word atin, A'tin is pronounced like the eighteen. This was intentional, as the number 18 always comes before 19 and there can be no SB19 without their A'tin.
