From reverse fan gifts to Youngbin's surprise visit, Inseong's rockstar-level solo debut week

SF9's Inseong for his first solo album 'Mute is Off' activities

She perfectly pulled off glamorous styling, such as red hair, gold jackets, and see-through sleeveless tops, on every music show.

Each and every one of the stages that proved his solid live skills befitting SF9's main vocalist feels like a precious gift.
