Hotaru and Hananoi-kun's plans to spend his birthday together fall through when Hotaru has a family event suddenly crop up. The thing is, even while she's with her family, she just can't stop thinking about him...
I mean, it's his birthday. 
You only get your day once a year.
.لا يحدث عيد الميلاد إلّا مرة في السنة
Es su cumpleaños.
Solo pasa un día al año.
Es su cumpleaños.
Solo pasa un día al año.
Tu sais, un anniversaire…
Ecco... I compleanni...
Sabe, é aniversário dele... é uma vez a cada ano.
У него ведь день рождения.
Он бывает лишь раз в год.
