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?
If I win, you'll have to pay for 
my lunch until I say it's enough.
.إن فزت، فعليك دفع غدائي إلى أن أقول يكفي
Wenn ich gewinne, lädst du mich
zum Essen ein, bis ich nicht mehr kann!
Si gano, tendrás que pagar mi almuerzo
hasta que yo lo decida.
Si gano, tendrás que pagar mi almuerzo
hasta que yo lo decida.
Si je gagne, tu paieras mon déjeuner
jusqu’à nouvel ordre !
Se vincerò, sarai tu a pagarmi il pranzo, 
finché non ti dirò di smettere.
Se eu vencer, você vai pagar o 
meu almoço até eu dizer chega.
Если я выиграю, будешь оплачивать 
мои обеды сколько захочу.
