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.

make out and stuff, too.
.لكن يمكنك تقبيله وما شابه
Oh .. Aber ihr braucht euch auch mit

Pero también podéis
besaros y eso si queréis.
Mais vous pouvez aussi vous embrasser,
ça ne me gêne pas !
Ma potete baciarvi e fare tutto il resto.
Non fate caso a me!
Mas vocês podem beijar, que não me importo!
