Idol ES gen collab:
After watching a little (only watched Meica's debut fully) it seems 2 of the 5 aren't really that comfortable talking in Spanish (Ruby and Akugaki). You can tell it by how fast and fluid they talk when they switch between Spanish and English, weird phrasing directly translated from English, and how much they rely on English when they can't find the correct word. I Would rate them Spanish wise from most to least fluent: Meica-Taiga-Lala-Ruby-Akugaki.
Or I could be completely off-base and their weirdness be due to Debut nervousness.
Also, the dynamic of fighting between each other seems a little forced sometimes and too real some others. Fingers crossed this shit doesn't explode in 3 weeks.
Edit: I thought it watching clips of her PL, but Lala's schtick (acting like an adorable baby who loves everyone) is cringe as fuck, especially in Spanish.
