Since this is AU, I'm actually changing some things. First of all, MinKey are not idols in this story. I know that BoA's concert ticket can be purchased by public but for plot purposes, I will make it similar to the usual Japanese concert system whereas you need to have a membership and it uses the ticket balloting system (I think it's quite the same as SWJ/Johnny's Entertainment ticketing system).

Thank you to Dea for being a great listener :)
