well if fans are rich enough they can do that
but i don't think so
in banmarinter ig they mentioned about the both parts so i believe if mark wasn't in the both part they would be precise about it but until now neither mark's fans or kim's fans said that they will be in one part so i will go with they gonna have concert from 1 pm until night

i think you can ask here in this thread to see if someone have more knowledge about that cause i really don't want to give weak information so will wait and see what will happen

personally i'm not expecting a wooow thing tbh cause ch3 they are not that great in making concert and also i'm not expecting MK to have that much time it will be probably a group dances with a cameraman trying to catch this and that , i will count more on the fans's phone camera and i'm more excited not to the actual performance but for the backstage
