On August 11, SF9 released both group and individual “LIGHTEN” concept photos, giving fans a first real glimpse into the visual direction of TENACITY.

With the official release just weeks away, the group’s promotional schedule is expected to ramp up quickly — teaser videos, highlight medleys, and individual member content typically follow concept photo drops in K-pop rollouts.

## Beyond the Comeback

While fans count down to TENACITY, two SF9 members are staying visible on screen: Chani and Hwiyoung currently star in the drama *Miracle*, streaming on [Viki](https://www.viki.com/tv/38648c-miracle). It’s a reminder that SF9’s individual members continue building strong solo careers even as the group prepares for a major group era.

SF9 debuted in [2016](https://en.wikipedia.org/wiki/SF9) under FNC Entertainment, and a decade later, they remain one of the more consistent boy groups of their generation — a rare feat in an industry known for short group lifespans.
