Umino Nagi was swapped with another child at birth. He’s going to meet his real parents today, but on his way to school, he meets a girl who is threatening to die to get out of her engagement.
Nice to meet you. 
You must be Nagi-kun.
.سررنا بلقائك. لا بدّ أنك ناغي-كن
Guten Abend, du bist also Nagi.
Piacere di conoscerti, tu devi essere Nagi.
Muito prazer. Você deve ser o Nagi-kun.
Значит, ты Наги? Рад знакомству.
