Hakari and Karane learn that Rentaro hasn't had his first kiss yet. They may both be his girlfriends, but they still want his first kiss for themselves!
That way, you'll both be equally 
likely to have had my first kiss.
بهذه الطريقة، كلتاكما سوف تكونان
محطّ قبلتي الأولى
So wären beide von euch mit gleicher
Wahrscheinlichkeit mein erster Kuss gewesen.
Para ello, ambas tendrán la misma
probabilidad de llevarse mi primer beso.
Así tendréis las mismas oportunidades
de llevaros mi primer beso.
De cette façon,
vous aurez chacune autant de chances,
Così facendo, le possibilità che il primo bacio
sia con ciascuna delle due saranno uguali
Dessa forma, as duas terão a mesma
probabilidade de terem dado meu primeiro beijo.
Тогда вы с равной вероятностью
будете именно той, кого я поцеловал!
พอทำแบบนี้ก็จะมีความเป็นไปได้เท่าเทียมกัน
