I love Gemini and Fourth both as actors and as acting couple, but this is not their best work.
Unfortunately it happened automatic for me the comparison with the japanese version, since I have watched it first years ago.
For me the japanese one was the best one: the actors were perfect for their characters in the drama, I also loved the delicacy with which the story was approached and the secondary characters were always inserted into the story in the right way and at the right time. They were never an extra.
Gemini and fourth are good actors, I loved them in "My school president" and I loved even more their characters in "Moonlight chicken" so I don't doubt their acting skills. But this was not their drama.
Maybe if I didn't watch the japanese version, I could've thought differently, doing no comparison. But the reality is different.
I have tried to watch this version until the very end only for gemini and fourth, but I couldn't.
In general, the drama has a very good plot so I can't say anything about it.
BUT IF YOU WANT MY OPINION, GO WATCH THE ORIGINAL VERSION E LEAVE THE THAILANDESE ONE APART AND IF YOU WANT TO SEE GOOD WORKS OF GEMINI AND FOURTH THEN GO TO WATCH THE DRAMAS THAT I HAVE NAMED BEFORE.
