"Oshi no Ko"

Mangas about acting, though Oshi no ko has a lot of dancing/singing/idol activities too, whereas Kasane focuses just on acting.
In both the protagonists have a dead parent who was a legend in show business with mysteries surrounding them that protagonists unravel slowly.
Both feel melodramatic at times.
Kasane is more supernatural and darker, whereas Oshi no ko has a lot of lighter and comedic/endearing segments.
