I love unique stories and this one embodied that. Yes, everyone hated the ending, but to me I was satisfied. Probably because I was so impressed with the intelligent story telling, directing, cinematography and of course strong acting leading up to episode 16. The journey that this screenwriter takes you with their careers and their awkward yet beautiful relationship was truly beautiful. I don't think I've seen writing like that and the way the director and the actors carried out that story is what keep me so engaged with this drama. It was so unique and lovely. Relationships are about the journey and yes about the end game too, but think if it were a happy ending, you'd probably say that was good and move on to your next drama. But nope, you're still here, you're still thinking about it and maybe yes you're upset- but the writer made you think and that's what they want. That's their happy end game. This one will be in my 10 ten of all time.
