―Aaron O'Neill

Aaron O'Neill is a minor character in Sibling Rivalries. He is the middle son of Ethan and Chloe O'Neill, the younger brother of Dillon and the older brother Robert. He is also the cousin of the McReary siblings, which are the main protagonists of the series.

Aaron is a mix of a gothic (although he does not have any black in his clothing) and a very sensitive boy. He always appears very sad, and usually appears with his hands in his pockets, and earbuds in his ears, which shows he is listening to music. His younger cousin Kate McReary thinks he is cute, but she knows they cannot date, since they are related.

Aaron currently resides with his family (as well as his uncle Cameron O'Neill) in Appleton, Wisconsin.
