The cheerful and youthful girl group, Year 7 Class 1, are gearing up for a comeback. They've been doing quite a long-term teasing project as they've been releasing pictures since March, and they added new ones just recently.

It looks like they're going for a more mature yet still innocent concept as the girls dress up in simple white shirts.  Adding a complexity to this concept, the girls can also be seen looking tough in school uniforms with intense gazes, suggesting a big change from their innocent, cheerleading image.
