Stray Kids’ mixtape “OH” along with its music video was released on the midnight of June 26 KST in Youtube and music streaming platforms.

Fans were shocked as there had been no teasers, trailers, nor an exact date regarding when the mixtape was going to be released, making it a surprisingly released single with no promotions.

On top of that, the mixtape also marked the return of their member Hyunjin, who had been on hiatus since February of the same year.

The morning after the mixtape was released, their agency JYP Entertainment, announced that Hyunjin will be rejoining the group’s activities starting July.

Since the start of July, Hyunjin has become active again in engaging with their fans particularly in JYP Bubble, a paid platform that allows fans and artists to send messages directly to each other.

Moreover, Stray Kids is confirmed to be preparing for a comeback this August.
