Hey, this might be a tough question :D
When watching J-Drama I often hear the word げいん (or げいいん) but I can’t find it anywhere in the dictionariesThe only thing I find is “ゲイン = gain” but I don’t think it’s what I’m looking for, or is it?
Here’s an example sentence:
This is from Last Cinderella Epsiode 9, one of the cast got hospitalized and they asked the nurse if it will get better soon, but she didn’t answer, and then someone said
日々の小かつが「げいん」でしょう
I’ve heard this word so much in several dramas, it’s so frustrating xD
Thanks very much :D
