In order to try to get Aki to promise to go on a date with him, Masamune teams up with Kojuurou and challenges Aki and Yoshino to see who can get a better score on a test. If he wins, he gets a date with Aki. If he loses, he'll have to live with the nickname Aki gave him until he graduates. How will this end up?
Am I okay with giving my first time 
being called by a girl to Koiwai-san?
هل أنا راضٍ بكون كويواي-سان 
الفتاة الأولى التي تتصل بي؟
Soll mein erstes Mal, dass mich
ein Mädchen anruft, mit Koiwai-san sein?
Una chica me llama…
Una chica me llama…
C’est le premier appel
venant d’une fille.
Una ragazza mi sta chiamando...
Será que fico feliz de a primeira ligação 
que recebo de uma garota ser a Koiwai-san?
Нормально ли, что первой 
позвонившей мне девушкой станет Коиваи?
