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...
She's done a lot for us, 
so I wanted to throw her a surprise party!
فعلَتِ الكثيرَ لأجلنا، لذا أردتُ
!أن أقيم حفلةً مُفاجئة لها
Ela fez tanto pela gente!
Eu queria dar uma festa surpresa!
Хотел устроить ей вечеринку-сюрприз
в благодарность за всё, что она сделала.
