Faithful

It's been 5 years since Atem left, now inexplicably he has returned with no clue why. He soon finds though that his new life isn't without challenges as he must now learn to accept that Yugi, while welcoming, has moved on. Complicated feelings plague him and all may not be as it seems. Can Atem learn to like Yugi's new beau? Or will his jealousy ruin everything?
