what do you mean by "contaminate my first impression"?

Also how did you manage to avoid all the pre-debut hype for IVE? I thought it was very big, given that it was Wonyoungs re-debut.
....
I think there was more hype for lesserafim n newjeans than IVE(EDIT: at least in my timeline, end edit), i avoided/ignored predebut stuff by being an ostrich with my head in the sand/being only interested in my faves/stan grps/casual likes/post-ing random stuff for dailys(since nov2020). It wasnt difficult in late 2021 for me smh to remain uncontaminated in my impression of IVE till
AFTER i watched ELEVEN MV on debut day.it was similar for me with aespa(i think i knew more abt aespa members predebut tho. I only stanned aespa later after debut, not before or immediately unlike IVE).
It might also be my brain cant contain everything(i know abt grps i dont stan/or even casually like eg. LOONA,dreamcatcher n mamamoo,IU,bol4 n others so not enuf room for new rookies/predebut in my brain space,LOL)
...
oh wow... you really like Running man. So you watch it every week, regardless of who is the guest

well its good the guests usually leave such a strong impression on you!
...
tbh i did tat only for a period of time, going backwards from the start to ard episode 150sthg or so-in 2018 to early 2020(episodes 310sthg till 480sthg i think-altogether overall more than 300 out of over 500 episodes); when i stopped watching commitedly due to no time/it was on cable tv every week but i wasnt in a location where i had access to cable tv (i did in 2019 to mar 2020). N i think iv forgotten guests who i had no strong impression of or who i wasnt reminded of later.
....
haha yeah like I said, I never followed IZ*one, I only know Nako because she is so tiny and cute
I only know nako as possibly one of the jo yuris(similar height n look to jo yuri) - yena, yuri n chaewon i think r others. I believe i cant identify/recognise nako or minju or hyewon to save my life (at this point i think)LOL
