Watch this for Cha Seung Won's acting. He is 100% absolutely amazing in this role. I was completely invested in his character from the beginning all the way up to the very end. I think that is why the ending disappointed me so much. Cha Seung Won's acting makes you really connect with Jiwook. To not have a clearer resolution to his struggle within himself just...left me wanting more. Left me wanting a happy endng because he deserved it. This movie deserved it. I would have given it 10/10. That being said, I still highly recommend watching it. The disappointing end is still worth it to see Cha Seung Won's portrayal of Jiwook.
