Starlight's new life with Twilight has been steady. She's making new friends to fill holes she didn't know she had. But there's one friend who's been missing for years: the one she misses the most, the first one she ever had. She hasn't seen him for years and doesn't even know if he remembers her.

With a new leaf turned, Starlight decides to try to rekindle her friendship with Sunburst. But will he remember her? And will he accept her for who she is now and in spite of what she's done?
