kpop1-7, Exercise 3: Fans

Model answer:

"Parasocial kin": fans create a familial connection with their idols rather than just being "look-from-afar" fans; some trainees already have their own fans before debut, so the "kinship" starts early.
Ways fans and idols meet (any two): fan meetings (artist engagements), concerts, fan sites, artist cafés, the annual convention KCON.
Ways companies limit fan activity (any one): some fan projects must be approved by the venue or the idols' company; fan connections with idols usually still go through the company to be approved.
Not covered (any two): fan chants, voting (including on survival shows), albums as merchandise, lightsticks. The articles I read do not describe them in detail, and writing about them would be from memory.
