They come back to the very very very past time, it was the memory of the original butler. So Gongja, who should be part of the butler (now), cannot remember anything. He still have his skill and stuff, but since he regressed as the "butler" he doesn't even aware of the skill and act like the butler instead . He still have some random memory with his lover tho, so he unconsciously come to Lady Laviel's place. Laviel was the only one who remember their memories together so now, as Gongja doesn't even remember anything, he became Laviel's trauma. Everytime she killed her, Gongja will looking into her memories with him. It's like an operation to make the butler realize that he is Gongja.
HELL NOOOOOOO. WHY RAVIEL HAS TO BE THE ONE WITH THE MEMORIES Σ(っ°Д °;)っ
