Yeah, I know this is a little tough to read, but squint hard enough and you'll be able to read the whole thing.
Too many fans live in this world of fantasy (and here you are, expecting me to link to capsule's World of Fantasy again, aren't you?) where members are promoted equally and have the same popularity. In the real world, nothing is fair, no matter how much rhetoric you hear in life about how everything should be fair.
In regards to this post on Kpop Secrets, Naeun gets promoted more than Eunji does. Naeun has been in a few dramas and was on WGM. Fat Chorong was on the cover of Heifer Hysteria, the go to porno magazine for chubby chasers. What more could they need? At least they're not in Yookyung's situation.
