"I Became A Star in a BL Drama" is, at the time I am writing this review, one of my Top 10 Comfort shows. It has everything I love:

* the runtime is not too long, so it's perfect for a rewatch in between new dramas,
* it is a sweet and beautiful love story with some tongue-in-cheek tropes, that makes me fall in love with the way the main characters fall in love,
* there is some character development, that links past and present, and gives some depth to the story,
* side characters have their own story to tell,
* the production value is high, in every aspect: I love the clour schemes they chose, the details on the sets, the make-up and hair dressing (which uses different styles for the characters when they are Akafuji and Aoyagi vs. when they are acting in the BL),
* Abe Alan and Akutsu Nichika play both of their respective roles very well, and are able to give them very distinctive personalities -- I love it when the director shout "CUT" and the BL character vanish, leaving Akafuji and Aoyagi behind,
* every actor in this is fully immersed in their role -- for some scenes with lots of characters, I like to rewind them, just to watch what is going on in the background,
* it's making fun of the BL world, with the feathers and the adoring fans, the tropes used in the "BL Drama" of the series and more,
* it's also a commentary on the film industry, how hard it is for child actors when they grow up, and the toxicity of fans,
* and the humour is my kind of humour, this Japanese kind of slapsticky over-the-top humour that some people can't stand.

Overall, I can't find anything I dislike about this, it's perfect for its runtime, has a simple plot on the surface but those who want to can also find some deeper meanings.
