Finally watch this after I can't keep my curiosity anymore for this re-make. Quite happy to watch this...

If I draw 1 conclusion between Thai & Japan version, for me the Thai is more like down to earth or more connected with me. I don't know is it because my country is closer to Thai than Japan, so I can relate more with this version. Or maybe because it just have more episodes, so they have more duration to explain some stuff. I'll try to explain it as much as possible...

The more 'down to earth' or what i more like:
+ The growth relationship between Achi & Karan better than Adachi Kiyoshi & Kurosawa Yuichi. I can't really explain how, maybe i just more like it....
+ The way Karan look into Achi is more obvious than Kurosawa to Adachi. The Thai version is kinda have broke 4th wall rule, we can see several times when Karan smile behind Achi, the smile that have obvious meaning....
+ The viewfinder of Karan toward Achi. We see how much care Karan of Achi. This proven by the speech Karan give about Achi in company gathering or the little gesture that Karan did for Achi everyday. I don’t remember such things from Japan version, maybe I'm wrong, or it just not too deep imprint in my mind...
+ The cuter Jinta than Tsuge Masato. And that's make the relationship between Jinta & Min is cuter too.... But at the same time Jinta is really one stereotypes characteristics of Gay man.
+ The strong Pai. I really like the strong & quirky Pai. The way she burst out to her ex is really fun to watch....
+ The 'dumb' Rock. Although Rokkaku Yuta is also a little 'dumb'. But I feel Rock is more innocent vibe than Rokkaku & that's make him cuter too...
+ The relationship between Pai & Rock. I really like & happy Thai version make the relationship between Pai & Rock happen.
+ A little Japanese touch. Yeah this one specifically for this version. I like they still make the boss be an expatriate that comes from japan, we can hear from his accent.
+ The growth in Achi. In here we can see Achi want to grow in his career. He consider quiting cause he feel his career is go nowhere, so instead allowing Achi to quit,his boss offer him new position. In japan we see no such, Adachi quite comfortable with his position in the firm. Yeah I know, this much have connection with Japan office culture.

The minus from this version is maybe that Karan put too much effort for Achi, so it seem imbalance for their relationship. I mean when Achi want to move city & they decided to separated beforehand.

Overall both series is good in their own way... I quite happy to watch both version.
