Why did CA Cupid from Monster High transfered to Ever After High?

Some Monster High fans did not want CA Cupid to go to Ever After High. This is because Cupid's mother Eros is basically a half monster and half angel. Cupid had to leave Monster High because she had relationship problems and
wanted to start a new life start at Ever After High.

Here is a video of a Ever After High Episode with CA Cupid

In the Ever After High True Hearts day episode, all princes and princesses students had good advice from Cupid than at Monster High. Here is the Monster High Cupid Episode:

I don't know what will happen this year or next year in 2015 but I am thinking there might be an episode of Cupid and went to visit Monster High but I don't know.

Ever After High will be around for 5 years and Monster High will be around another 2 more years I think.
