Let me just say, if you want to watch this kdrama, better two boxes of tissues cause of boy, are you gonna cry. I originally watched this to see Lee Kwang Soo, but now I am at the last episode and I just wanna say D.O from EXO is not only an amazing singer, he is the best at acting at heartfelt in my opinion.
I sincerely recommend but for a heads-up, you might not like the leads at first but the character development will sure change that!
