I’ve already watched the korean version when it aired, and it is one of my favorite kdramas to this day, when I heard that they were making a Japanese version what made me excited was Miura Haruma! And as much as I like him I’ll try to write my opinion without being biased.
I feel like you can’t review this drama alone without comparing it to the original version and as much as I'd like to do this it’s been a long time since I watched the K-version and I forgot some of the details to be honest, but as far as I can say the K-version had 6 more episodes while this like most Jdramas stopped at 10 therefore the K-version had a lot more time to explain the plot slowly and more thoroughly, while this version was a bit rushed in my opinion.
They obviously made some changes with some of the characters and minor plot lines but nothing too extreme the story is still the same.
Cast choices when it comes to male leads were good in both versions, and if we’re talking about the daughter oh my god both little girls were so good and cute I wanna meet them both and give them a big hug ❤️.
IF you just watched the K-version recently and now want to watch this version I recommend you wait a little longer before watching this so the story is not still fresh in your mind then you can enjoy it more.
And if you’re wondering should you watch this or the K-version I’ll tell you that the story itself is so good and it doesn’t matter which one you should watch cause you’re gonna enjoy it no matter what.
