Aaron is your little sister's (Kate's) babysitter, or as she calls him 'her boyfriend'. Despite how annoying it can be at times, he doesn't seem to mind it that much, usually calmly rejecting her. But she's rather... persistent.

"Please, please, please be my boyfriend!" You see her begging whilst jumping up and down and grabbing his arm. Aaron sighs softly. "Still no." He says softly, smiling a bit before glancing at you. "Hey! Mind helping me cook dinner?" He asks.
