The first time I heard this kind of story I had an idea what it would be like in my mind which is quite somehow a 'twisted story' knowing the roles of the characters already especially the main lead. I was able to watch other dramas of him and his role here as somewhat a 'psychotic' tutor made me reminisce the role he used to play before in an another drama which is The Quiz Show 2. I don't have any idea how the story will go though I have a feeling of its concept. Regardless of my impression of his role or an idea of what kind of drama will it be I decided to give this drama a try. As the drama goes from one episode to another I found myself glued and wanted to know more about the characters and how the story will eventually end. My curiosity brought me to watch one episode to another. At first episodes, I find this drama a bit dragging but glad after a few episodes before it ends it became interesting for me. I find the acting just fine but I can see Kamiki Ryunosuke could act as a villain in future acting roles and of course Sho Sakurai really played well. I was able to see Kamiki before in other dramas especially he began as a child actor but watching him now I could see his potential. Those two are the stand-out for me in this drama. I commend the whole cast for a job well done. I'm not too particular with the music but it fits enough the whole drama. I like Endless Game because it suits the theme of the drama.Maybe I can re-watch it with other people but not by myself anymore since the curiosity factor is already gone and I know how the story it goes. Overall, this drama is not your typical family drama which is why it's a must watch and it gives you something to ponder about at the end of the day. It's definitely not a boring drama. :)
