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...
It's completely turned into carbonara!
!تحولت إلى كاربونارا بالكامل
¡Ahora de verdad es carbonara!
¡Ahora de verdad es carbonara!
C’est carrément de la carbonara !
Ora è una vera e propria carbonara...
Agora virou carbonara mesmo!
Теперь это чистой воды карбонара!
