It's good to watch. The male protagonist's first group disbanded because of the aura of passers-by and the member's black material. After the protagonist returned home to settle down, he re-formed the group and shined. No cp.
It's not bad. The female college was forced to participate in the audition. Because of the fans and the charm of the stage, she gradually fell in love with the stage and shined on the stage. It's a bit realistic and cool. It's a girl group without cp.
