I guess it's 18+ because of the friend with benefit relationship and some drugs (medicines etc) but honestly idk, I just took the information from the trailer
What really annoys me is Ying. I know the characters must be different from each other, but it's the same in every series. Then there's a 'gossip girl' with an attitude. And there's another 'playboy' or a 'strict boss' (don't forget to mention the 'childish one'). I'm pretty sure no one in office life is that over the top in real life. But it could also just be to make the series a bit more 'fun', which annoys the shit out of me. Like, cmon. Office life isn't that funny? Anyway, I like the way the show shows an information thing in the corner of the screen with every English word they say.
