Twilight has been working on her dissertation on friendship but she wants to research an unstudied form. Mentors becoming lovers. The only person she can think of for the task is Vice Principal Luna, who has always been there for her. What will Luna say? What will she choose? Is Twilight really doing this solely for research? What about this strange feeling in her? Does Luna have it too?

Again Twilight is of age, this is not Foalcon.
