Koizumi-san is a reserved and mysterious high school girl.
Her classmate Ohsawa Yuu is very interested in this new transfer student. 
One day on her way home, she happens to see Koizumi-san in a long line in front of a ramen shop, which leads to them eating ramen together, and yet...
Oh, she's back to normal.
.آه، عادت إلى طبيعتها
Oh, das ist wieder
ihre alte Miene.
Volvió a la normalidad.
Volvió a la normalidad.
Elle est redevenue normale…
Ah, è tornata come prima.
Ela voltou ao normal.
О, снова прежняя.
