I've watched this movie countless times because it's so good and so well made. I love how past and future meet up, how they grow but also I love the end that gives you a little easter egg at the start of the first episode but you don't know till the very end. I loved how they talk about the born of the Hangul alphabet without being heavy like a historic drama could be. The cast is super funny, they made a really good job, i've cried at the end because is supoer sweet and unexpected. All 10 stars but all deserved!!!!!!!
