Honestly, first time I watch this series I feels like Sam is a bit weird character and Freen seem like not to be into Sam's character at all
Surprisingly, when I continue watching it, it made me realize that oh this is really Sam and I fell in love with this character more and more.
My most favourite episode would be Ep.5 when Sam stared to express her feeling in her own way, it's so funny, charming, cute and lovely at the same time
Another best episode for me would be Ep.11 where lots of emotion in same episode, fighting for love, loving each other's in the most sadness day, and fighting with yourself to be dare for love
And now even one year passed, I still rerun this series almost everyday randomly from episode to episode based only mood on that day.
