I didn't see this ship coming at all before the anime, but I'm already a fan. They even come with their own ship name!
Btw, the artist's comment was: "KuuKaa is precious... KuuKaa-chan is precious... Kanon-chan and Keke-chan are both seriously...precious... Superstar Episode 3 was the best..."
Yeah, Keke's name is written like Keke in English, but it's actually pronounced "Kuku."
Keke put their names together, and came up with KeKa. It's KuuKaa to pronounce it, but it can also be written as Keka, with the Ke at the beginning being pronounced like Kuu.
I started to watch the series and I don't care if it's queerbaiting anymore... I love them together regardless if they are lovers or friends or something ambiguous uwu
