Engagement Cancellation?!
Lala lives together in Rito's house as if it was natural.
According to Zastin, going through the official formality of Planet Deviluke of telling one's feelings by touching the partner's breasts has officially established the two's engagement.
Being told by Zastine that saying it was an accident or misunderstanding was the same thing as declaring war against Planet Deviluke and that Earth would be destroyed, the color drained from Rito's face.
Even so, he manages to learn a way to cancel the engagement, but it was to touch his partner's breasts once again within three days of the engagement establishment.
Aiming for Lala's breasts, Rito's hard struggle begins.
Last line kind of sounds criminal.
Sure seems to be one screwed up planet and formality, Deviluke is...
