Great chapter! Definitely worth the build-up from all the previous chapters. We get to see some really good Suryeon characterization for once, I think this is the first time we get her first internal POV and thoughts. I was convinced that Suryeon would be serve as a foil for MC if she were to follow Iruha's footsteps and coaching (and all the mistakes she made with it), but I guess I was only half correct(?) She had the same type of breakdown as she did during the tv show performance but it seems like the catalyst of her breakdown was because she was rejecting following Iruha's footsteps?
I really don't know what to make of it though, considering this is the first time we get her genuine emotions and thoughts and it turns out to be the opposite of what it looks like from the outside observer looking through Suryeon's action (which seemed to be following Iruha's footsteps exactly.) Really the breakdown is far more similar to Yoil's rejection of Iruha motive-wise, stemming from her desire to be different from Iruha.
She seems to have managed to keep herself together enough up until she had to get off-stage. So, I think she's safe for now. It's nowhere near as bad as Iruha's breakdown live (whereas this is just the monthly eval) and she managed to debut! but it's also bad juju for her considering I doubt the studio wants idols as err... unstable as Iruha for their break out idol group. Interesting to see more of her, looks like this is a turning point from her just being the sole antagonistic force of the story to something more complicated.
Mooyoung's and MC's conversation was pretty intriguing and eye opening. We get the themes of the story (identity/personas, people foisting their expectations on you) hammered onto you. Mooyoung was adept enough to notice her mistake and apologize for it, which I massively respect. But it looks like she wasn't too far off anyways, MC does prefer Mooyoung taste's over the ones expected of the idols. But she's hard-headed enough to mask that and show the version of her that is desired by the idol industry instead in order to stay ahead. <-- but she realizes this flaw of her and probably wouldn't be so much of a tryhard next time.
Though it does seem like for the solo performance, Yoil 99% will pick a girly song in order to prove Producer Gu wrong in his assessment of her. She is err.... "bold" enough to want to show Producer Gu wrong, that she is infact skilled enough to be able to portray both the black swan and the pink swan at the same time (or whatever analogy that producer Gu meant by that). Having come to terms with her personal self and how she approaches femininity to choose out of her own free will to pick and stellarly perform a girly dance number. I guess that's a part of MC's personality, I like the MC for not being a total cardboard in terms of characterization. He does have a tiny bit of attention-seeking and egotistic streak (stuff that is actually a pro in the idol industry) while still being a generally nice lovely personable traits he has ontop of it. You can 100% see why she's born to be such a perfect idol. a multifaceted character that I enjoy.
As for the trainee eliminations, I'm honestly not so sure on who's going kaput. Team A is 100% fine, team B also barring Mooyoung, It remains to be seen how much of a slaughter it will be for team C
