Theo saw Ellie for the first time and new she was going to be his one. Ellie was too young though and needed to go to college so he bided his time but didn't realize Ellie was purposely staying away.

Ellie believed her sister had a fresh start at life with her new husband and didn't need her around anymore. However she didn't realize that Theo had other plans. which included a happily ever after.

Fun quickie. You get where Ellie is coming from but I wish the story had just been a bit longer to develop the background.
