One day, Koizumi-san leaves school saying that she has something to do.
Yuu is doesn't think anything of it, sure that she is talking about ramen again.
But of course, Yuu tails her again, and she sees Koizumi-san waiting for someone in front of a fancy western restaurant. When a dashing man appears she yells "Koizumi-san, don't!"
Then why'd you stand outside 
waiting to get in here?
لمَ انتظرت خارجًا للدخول إلى هنا إذًا؟
Okay, warum hast du dich dann extra
draußen angestellt, um hier zu essen?
¿Y por qué esperabas
afuera para venir aquí?
¿Y por qué esperabas
fuera para venir aquí?
Alors pourquoi avoir attendu
pour manger au comptoir ?
Ma allora perché sei venuta qui
e hai pure aspettato fuori?
Então por que ficou esperando
 para poder vir aqui?
Тогда почему ты просто не зашла внутрь?
