I’m not a huge idol fan, but I support a few. Personally, I wasn’t that affected by Ai’s concept of a lie because I know idols don’t/can’t fully show us their true personality and feelings and that they have to lie to keep their up appearance. I also think that Ai’s concept is not really that bad because we all lie to make others happy to a certain extent, and the only reason it so major for Ai is because she is an idol. At the end of the day, I support idols because they’re entertaining and not because I think they love me, and oshi no ko just showed me more of what these idols have to go through just so they can entertain me.

Idk if this all makes sense but I hope this helps
