@@APEX-SS 『 相性』と言う意味合いで使うのは間違いないようですよ。 アメリカでネイティブな使い方として、『I think we have good chemistry.(彼女とは相性が合いそうだよ。)』とか『The chemistry was right.((面接とかが)上手く行ったよ。)』みたいな感じでよく用いられているそうです。 アメリカ人ではよく使われる表現の1つだそうで、なかなか日本人には馴染みがない表現のようですね。
Me too when I first listened to piece of a dream I was at my 14 or 15, the harmony they sang was just perfect and I started listening to their music until now, I still have their songs in my sportify play list.... But I never understand why they cannot be as famous as some other boys group in Japan may be they are not considered as the mainstream?? Personally I think they are having the best voices among all groups there...
