Oshi no Ko manga hasn't reached its conclusion. It continues to captivate readers with its evolving plot and characters. So, keep an eye out for the latest updates if you're a fan!
Oshi no Ko is indeed a weekly manga. You can expect new chapters to come out every week. However, there might be occasional breaks or delays due to various reasons.
You could create a fanfic where the main characters time - travel back to their previous lives. This would add a whole new layer of drama and mystery to the story. They could try to change things or gain a new perspective on their current lives.
