So, I read an interesting article from an anime news website that talked about the differences between how Westerners and Japanese view their own idols/singers in real life.
To sum it up, the West views idols/singers as simply people with talent like a career. They are there to put on a good show. So, it’s okay if they do stuff what normal people do such as fall in love, etc. As long as they don’t do something that’s illegal.
However, in Japan it’s very different. They view idols as an “illusion”. Basically, a perfect doll whose purpose is to make fans dream about being with them. So, if they do anything “impure” or fall in love, then the fan’s “illusion” will be destroyed since their idol is not a perfect angel and cannot fantasize them. After all, their idol is in love with someone else, so they can’t pretend to be with them.
The Japanese negative attitude towards idols falling in love has influenced many idol animes where the idol characters strongly despise the notion of falling in love by saying it’s a scandal and it’s wrong.
But, I do remember Wake-Up Girls addressing this controversy of idols being unable to love someone else.
Idolm@ster is one of the few things that I believe actually doesn’t really follow this formula 100%. There was one manga (Idolm@ster mana) where a few idols were discussing about why they can’t love. But, for the most part Idolm@ster (including CG and ML) avoids this especially since the main protagonist (the producer) represents you. Of course, most of the time the idols are just teasing or having a crush. But, other times some idols fall in love. One example can be seen in Chihaya’s story in Idolm@ster 2 and One For All. I’m sure there are other examples of CG and ML characters who are seriously in love with the producer. And, it’s why I like Idolm@ster more compared to the other idol franchises where the concept of falling in love is strictly forbidden.
I personally share the West’s attitude and believe idols/singers should be able to fall in love since their work is a career.
