Hayato wants to get Shiragiku a birthday gift, even though he's two weeks late. Akane helps him choose one, and on their way home, he remembers that today is Akane's birthday. He offers to buy her a gift as an apology, but she only wants one thing...
I wish she would've told us 
her birthday was already over, though.
أتمنّى لو كانت قد أخبرتنا بأنّ
عيد ميلادها قد انتهى
Sie hätte sagen sollen,
dass ihr Geburtstag war.
Ojalá nos hubiera dicho
que ya pasó su cumpleaños.
Ojalá nos hubiera avisado
de su cumpleaños.
Quand même, elle aurait pu le dire,
que j’avais zappé son anniv.
A ogni modo
Mas eu queria que ela tivesse falado pra
gente que o aniversário dela passou.
Она могла бы и сказать,
что у неё был день рождения.
