the first season of produce 101, this season we have 101 girl's trainees who are going to form an groupe of 11 girls called IOI

101 trainees are together in a show, waiting for the votes of the citizens who are the national producers to form a unit of 11 boys called WANNA ONE

this show is kinda similar to Idol school, also a survival show for 100 chinese trainees in order to form a unite of 9 boys

I like both those series since they bring idols groups or singers,
while watching them, you will laugh to your heart content, weekly idol is also known for teasing and picking on the idols
they are both great shows

it's not excatly the same plot but in both series the female lead is able to see ghosts.
if you liked Ghost friends I highly recommend watching the master's sun
