Sasuke used Madara's Eye of the Moon plan to successfully transform the world, but unexpectedly everything went back to when he was born. Sasuke lost his memory about the future but retained his abilities. Itachi is still the gentle brother, but his feelings for Sasuke have undergone subtle changes...
PS: Corrected version, Itachi, your cup is set. The original Sasuke is different. He has deep feelings for Itachi and is not limited to family affection. He is unexpectedly clumsy in feelings. Followers of self-interest.
Contains ALL ingredients, but the main ingredient is Weasel (although I don't really like Weasel GG)
... And above.
