This whole "holo promise" thing is just them subtly asking you to stop bringing Sana up, they dont care about her, Sana doesnt care about them, forget about her. She barely streamed while she was in EN, she was mocked constantly for only having 2 jokes (beeg, bread) which became uncomfortably obvious during one of the Council collabs where everyone else was chatting normally and she could only communicate by using her two unfunny memes. She was in for less than a year and it's already been more than a year since she left, none of the other Council members bring her up unprompted so why are you.
