Mukai Naoya is in a relationship with Saki Saki, but another girl, Mizuse Nagisa, asks him out. He makes the unthinkable decision of asking them if they would be up for both dating him at the same time.
I can't bring myself to date 
both of you in secret.
.لا يمكنني مواعدة كليكما سرّا
Es ist so: Ich brächte es nicht über mich,
insgeheim mit euch beiden zusammen zu sein.
En gros, je veux pas sortir
avec une autre dans ton dos.
Voglio dire che non posso accettare l'idea
di frequentarvi entrambe in segreto.
Não posso sair com vocês duas em segredo.
Говорю же: ну не такой я человек, 
чтобы изменять тебе тайком.
