Oshi no Ko

This anime can teach a lot of writers on how to write a good script and how to execute it and take it to the next level.
The story just pulls you in. At first, I thought this was a movie as the first episode is 1.5 hours long. But I understand why it was done in such a way. So that the viewer gets sucked into the story and keeps watching. It's easy to watch a 24-min episode and then completely forget that this exists, if you'd have not watched the first 1.5 hours of the story.
