I REALLY LOVE THIS DRAMAAAAAA:
Why? It's just perfect for me... It touched my heart.. I can't really explain but yeah this is totally worth watching BUT here are some things that I don't really like about, but it's just for me: well one thing is that it doesn't only focus on the relationship and lives of two people, it also depicts the life of three others, it's not that I don't like the three others, it's just because I want to know more about the two but their scenes together are kinda too short for me(their scenes are actually flashbacks of their relationship), and I kinda get bored whenever it's the time for the three actually their four heheh....

But overall I loved it!!!
WAIT!!! Make sure to watch this, BUT BEFORE IT, you should get your tissues ready, okay?
