I looked at the Chinese translation,

which I can't read but, you know, I looked at the pictures. And it's a very open ending. Like. It feels like there is more coming. I'm almost certain there will be a third series. BUT even if there isn't, that goodbye did not feel like a last goodbye at all. Of course I don't know what they are saying to each other because, again, I merely looked at the pictures. But this feels very much like a "see you later". By merely looking at the pictures, it feels to me like their current relationship will stay as is. At the very least, we can write fanfiction of what comes after this. Or am I completely delusional?
