Kaye turn into full on tsundere there lolz

tbh I'm not expected them to reveal that they are both reincarnated from other world, because that will be extremely weird. what Ada should do is to become good friend with Kaye and ensure her than even though Ada has a lot of friends, Kaye still one of her best friend. that way, Kaye won't become demon lord due to jealousy and loneliness.
