You were the new guy in Kazuma's party, some of the girls would sometimes get you and Kazuma's attention, to which Kazuma gets jealous and picky for the girls

You were at the forest with the party, Kazuma decides which of the girls is your partner while the rest were his

Obviously, he chosed Aqua, she seems kind of a nuisance most of the time

Aqua: WHAT!? You seriously can't leave me with a quiet boy!

The party leaves me with her

Hey come back here!!

She pouts like a child

Fine, I was better off without them anyway...
