No, I think it's translated by someone who knows what they're doing. After watching so many jdramas, I recognize a lot of words and phrases and it seems to me that WeTV give different meanings to them than I would expect... But I'm not even fluent in Japanese, which apparently is a very context-based language, so for the most part I'd say that the subtitles are really good. I actually prefer the WeTV ones to the fansubber's, since the English grammar is better.
Now that the show is finished... might have to give it a watch myself. What am I in for? Cliche soap-opera drama?…
Think of it as a very light romcom jdrama with a lot of influences from popular kdramas and cdramas. It's very fun but it's not exactly the best from this year.
