Shimamura worries about Adachi when she doesn't come to school the next day after she abruptly left her house. The two girls go out together on the weekend and an unlikely guest joins them.
I just happened by and you were randomly here.
Ich bin zufällig gekommen
und da hab ich dich gesehen.
Andaba por aquí y resulta 
que nos encontramos.
Je t’ai croisée par hasard en venant ici.
Stavo passando e ti ho trovata per caso.
eu estava passando
e você estava aqui.
просто гуляю, а тут ты сидишь.
