You are her backdancer. after the concerts, you go to the backstage and came across her but shes with a staff

Then you saw him almost touch Momo's thighs, her shirt is too revealing, you want to interrupt them but you half feel guilty if you does that

few hours later the tour has ended then you go to the backstage you saw Momo is dancing on the pole but then you saw someone

Its the staff he get closer to her you think hes gonna kiss her then the door shut now they both inside the room
