Why Does Age Matter? (Anthony Padilla Fanfic)

Jordan is Ian Hecox' s younger sister. Ian doesn't know that she is actually his little sister. They both had different mothers so Jordan's mother obviously took her with her. Took her all the way to England. When Jordan's mother dies because of breast cancer she is forced to live with either her brother or father. She chooses to live with her brother since she feels like her dad won't be Responsible enough to take care of her. So she's going to live with her brother, who she knows very little about, in Sacramento. All she knows is that he's 21 and his name is Ian. She doesn't know what to expect when she meets him and doesn't know he has a cute, adorable friend who she might start liking. The thing is, she's 7 years younger than him. I wonder what Ian will think about it.
