For me, it's Lightsum. I thought Cube learn from their mistake on how they handle CLC and how Soyeon trying hard to direct G-idle to the right path, but unfortunately, they're not learning at all. They didn't give the girls clear concept and image the way they did to CLC and it's probably too late too with all these popular groups debuted now? Their sales drop when most gg now show some improvement. From 41k at debut to 17k for their latest cb. Their predebut teasers were leaning towards something innocent and elegant similar to Lovelyz, then their debut was this weird mix of bubble gum and teen crush, I guess and then Vivace was elegant in a way reminiscent of Izone. And people call them the cheap version of Izone. No strong identity whatsoever. Which is reminds me of CLC who were constantly switching back and forth between different concepts which made it hard for them to establish themselves.
