I have never written a review my whole life... I'd not write a whole lot but I just want to say to whoever is reading this just leave everything and watch this kdrama this instant.
Even tho I was hesitant at first to watch it but after I started this... I couldn't stop. I have never cried sm in my life...
Indeed this is one the best drama out there. So, just go and watch this. You'd not regret it I swear.
