Im a fan of korean drama since 2016 and I've seen a lot of dramas from drama, thriller, romance, fantasy, sci-fi, comedy, idol, and historical dramas and I was actually amazed by this new actors. Honestly speaking idols acting in a drama was kinda awkward but because the story focuses more on idols I think their acting was real because they already have experienced a daily life of being a trainee turned into idol and I think its suited to have idols in this drama. And it was great seeing almost all of them know how to act properly and I'm still looking forward on what ending we will get!
