"STPR's first girls' group. That one step will become a new history."
About
STPR's first girls' project—its history begins here. STPR, which has delivered countless dreams, has taken a new step forward. Its name—"STPR GIRLS PROJECT." And chosen as the historic first group were four girls full of individuality. Starting their activities while carrying both expectations and pressure, the road was by no means smooth sailing. Their first recording, dance lessons that didn't go as planned, broadcasts filled with nerves, and finally, their first live performance. Though they hit walls many times and shed tears of frustration, the four of them gradually became "comrades." "We want to become someone's inspiration, too." A new story that no one knows yet. This is a growth story packed with youth and dreams, where STPR's first girls' group aims for the top while laughing, crying, and supporting each other.

A morning with soft spring sunlight pouring down.
Feeling my heart thumping deep in my chest, I looked up at the large building.
There, written in large letters...
──STPR.
From today, this place will be our new starting line.
