Luna won't you cry for me

"Luna won't you cry for me,
I'm lonely as i've ever been,
I am forced back into the start,
Is there anyway to fix a broken heart?"
Song: [link]

Boy! This song suited Riddle's little sister like sooo much!! And it's called Luna! XDD (which is also her name)

When Bat rebuild the loner group Luna joins it, and during her stay there falls in love with a strange passing by cat who seems to be part of a small group that never make up its mind if it want to join the rogues,loner or clan cats.
Luna refuses to join the loners when Bat and Gravity offer to join forces with the rogues. She tries to convince the tom to live with her with the remaining loners. But at the beginning he doesn’t. She is grief stricken, and thinks that he might love one of the other she-cat that is with the small neutral group. She grows cold, doesn’t eat, waiting for the tom to return…will he or will he not?

(I'm gonna just let you guess who the tom is, i'll just hint that he's a character of mine, to narrow down your search)
