I only just started it but so far it reminds me of that ryu jun yeol movie hit-and-run squad
I haven't watched that far yet I just mean it reminds me of bit and run cos of the whole car focused crime thing, it's fun and different. I do remember from hit and run the main guy was an ex criminal who was adopted (not sure if legally) buy the dad as a young adult and he went into being a cop focusing on car crimes or something but I don't know if that's similar I haven't watched enough of signal yet
I don't know if it's because of him or his character but for some reason in Uncanny counter he reminds me so much of hongjoong, I think his character and the new counter are my favourites ties with mum and motak now haha
