7-nin no Nemuri Hime

I want to wake up the princess who was put to sleep by a witch's curse… but there are seven of them!
So it seems that I have to kiss...... seven girls!
Now the princesses are awake, but the other people in the kingdom are still asleep...... Why?
Is there more to breaking the curse than just a kiss or am I still missing something......?

Alec is the third prince of Rudbekia who wants to save the kingdom of Amaryllis and its seven princesses.
In a country where only they are awake, they must work together to save everyone from the curse!
