Stray Kids proved they're a force to be reckoned with even at less than full strength. The group's highly-anticipated comeback landed on August 7 at 1 p.m. KST with the mini album THIS & THAT and its title track of the same name—and both immediately rocketed to the top of YouTube and iTunes charts globally.

As reported earlier this week, vocalist Seungmin stepped back from certain promotional activities while undergoing rehabilitation treatment. JYP Entertainment didn't specify the nature of his medical situation, but the label confirmed he'd continue to participate in select comeback events. The move meant Stray Kids would promote without their full roster for music shows, fan meetings, and other scheduled appearances.

That didn't slow them down. The release day numbers tell the story: "This & That" hit #1 on YouTube's trending charts across multiple regions and dominated iTunes charts in countries worldwide. The mini album itself followed suit, signaling that fans were ready for new music regardless of the circumstances.

Stray Kids have built a reputation for delivering polished, high-energy comebacks, and THIS & THAT appears to be no exception. The title track's immediate chart success suggests the song resonates with their fanbase—both the longtime supporters who stuck with them through Seungmin's absence and newer listeners discovering the group.

With Seungmin's health as the priority, JYP's decision to move forward with the release as scheduled shows confidence in the material and the group's ability to carry momentum even during a challenging period. Stray Kids have proven time and again they can handle the pressure of a major comeback, and these early numbers back that up.

The group will continue promotional activities for THIS & THAT in the coming weeks, with Seungmin joining in where his recovery allows.
