Meet and Greet session?

Hello to all MIR fans,

I read in one of the youtube comments that the MIR cast has an appearance/mini concert session at JJ Mall in Bangkok on 17th September 2017. I can't really find information about it and would like to confirm if it's true? I am interested in flying over to Thailand to attend the event (despite not understanding Thai language at all) . 

Please help! Thank you so much!
