... Huh. I guess old Arisa wasn't as sex-crazy as I thought she was, if Mari could get away with walking around topless in her presence without getting felt up/screwed by an enthusiastic Arisa (if that had happened, she logically would've been embarrassed and hesitant, not completely nonchalant and seemingly oblivious to how it affects her girlfriend).
