Yeah... Gugudan's debut song was so lackluster, I could understand that Sejeong and Mina fans only focused at I.O.I for the time being. They're a group filled with good vocalists and they finally release a main track that does them justice. I hope things goes good for them.
Re: Cuca: I don't think relocating was a problem for her debuting in H!P, if she won any of the past 5 H!P auditions. I'm sure H!P is not gonna let a family struggle like they did to Koharu back in 2005 again. The issue was that the other way to debut in H!P, by joining Hello Pro Kenshuusei, is basically impossible for her. The membership fee, the constant travel to and from Tokyo, etc. It's too much for someone who isn't from a well-off family outside of Tokyo.
But yeah, joining a AKB48 sister group is a good compromise.
She has been doing various 46/48 group covers recently and she said that Sashihara Rino is her oshimen. She must have been super happy knowing that Sasshi is going to be in STU48. Hopefully, she successfully passes the audition.
