no time for writing proper summaries so here is the notes I've made: 

dare to depict cruel competitions than friendship lol, people criticized that the hardworking 2nd FL always lost to prodigy less hardworking protag, but I think that's realistic,see the prodigy Morikawa Aoi always easily KO those special skills master who mastered their crafts for years; whoever critcized must be with kids mindset lol, using animes as emotional boost lolol

the protag also has her growth not only raw talent keeps her winning I'd like to emphasize — at first want to become similar to admired 1 & relying on effortless talent/potential (way better then normal “power” enticing much perfect than ✗accepted true unpolished self afraid worthless without) → Own style & hard-work make real self foundation reach overcome believe same level (eg. Sports good move but need very strong body foundation otherwise harm / high notes ease but also need good voice technique basics to support otherwise strain) stop rely & accept disliked side also self & harsh environment (friend left, headmaster harsh trial) but frds all offered help (untalented design talented designer bff friendship necessary once helped important dress get… ) then able to make everyone shine together w/ fans like saint Maria and overcome gifted power & truly congrat winner ✗care losing (eg. Ep 66) / hotaru — nice level but startup foundation responsibility sense ✗rest→gifted potential side effect reduce performance thus power boost vicious cycle regret over rely forget also frd support 

2nd FL — fans support saved her from depression lol, too care on win lose neglects individuality → (rock way of life & best on stage worst off), try best ✗depress ep50 / go believe self way means integrate own memory emotion (ep 63 inherit brand self motif too & refuse normal competiton but accept overseas scout), think career in-depth seriously (eg. Go my way copy worries & singing meaning & still fraction care win ep 86 waver), challenge / new discoveries growth freedom 

one chara body weak soul strong, questioned must follow others but difference & own pace own ways, determination turn reality even under harsh environment eg. heartless words look down, sing for herself because of the logic of can't move others with performance that isn't acceptable for oneself;

knight chara, talent but lack passion start only because others suggest ✗single criticism only her role model & simp blind by superior ones radiance admit then give up polish self will & past hide identity fake smile protect privacy →knight gentlewoman / supporting role solely for helping someone else shine brighter motivation not fans/self (unaccepted motivation but realistic ✗that pure holy "for fans sake" mindset ep64 role model criticized vs mahiru  compete higher even not win others improved self and make rival ✗lonely even improve (she surpassed the top ranker sister and not depressed when lost)? & brave use real name reveal unacceptable motivation (vs ep 64 share self exp anonymously) sincerity accepted by fans→✗want give up / admired one gone crazy thus follow mahiru suggestion become the light ie. others' new admiration and rivals her role model 

 the student council president, see genius flee (compete but own way so change troupe, many roads to Rome self surpassing, strict guide thinks should gain strength live on their own > loneliness rules must be followed unwillingly vs frds supports)

also some music industry related edgy things like, 

already internally decided candidates fake contest lol, 

strategic please judge rather than self charm

hierarchy that artists lost passion but still looked down idolish actresses only able to get role because also in charge of the theme song but the president brave without stunt and try best and break prejudice of connections showed enthusiasm

 ✗ride on family connection coattails hide background 

centralized once leader bye whole break down & true individuality can over high wall break harsh uniformity mold vs  decentralized individuality self prod
