Yes, as I was rereading 19 (because I always do that before reading a new one) I noticed Misora behind the tree, so I predicted he would come back, and I was right. Now, as sad as it is, I can feel the series coming to a close, and as much as I don't want it to, I am looking forward to seeing how it ends.
Anyways, as for 20, it is great, but I really don't know how much I can talk about, so let's talk about what Tsubaki said, that how he thinks there's a part that is gay and parts that can't accept it, that was a really well done scene. In Japan, being gay is taboo (obviously), and it's obvious he wasn't raised to love them, so I think by saying what he did, he is telling Takusu, he is showing that battle with himself, on the side that is gay and the side that hates them, a conflict I'm sure many gay people actually have to deal with. That was pretty cool.
