If you want to see something similar or exact same as Shining For One Thing then Blue Birthday is definetly for you. However i must warn you if you are up for a superb acting then this drama might not be for you since there are rookie actors in the cast. Personally for me, for a mini drama I think everyone acting was still better than some of the mini drama I have seen. Another thing might be since it's a mini drama the plots are not that exploits but it's definelty a worthy drama to binge if you are craving for a similar drama.
