I would rate this 10/10 but I think Ahn Hyo Seop's acting was a bit awkward. Don't get me wrong! I still like him, I saw his improvement in Abyss. I just thought that he could still do better. As for the lead actors, I just love them. I love their roles, the story, the sweet scenes, etc. I love the whole group too, their friendship made me feel so happy that I wanted to be included in that drama lol. It's just so warm and happy. They were always there for each other, blood-related or not. I hope they would produce more dramas like this.
