Mari-san, between these girls, which one is your type?

Wife and big breasts... The 'wife' here implies NTR.

Hmmm...

It's Arisa... I think.

Maaaan, just hurry and leave already!

Arisa: She lost her memories with Mari due to amnesia. Very optimistic.

Mari: Arisa's lover. She was the submissive one in their relationship prior to Arisa's memory loss.
