I have to say, to all those saying no romance happens in the so far released 8 chapters. I'd just like to remind you all, that basis of friendship has to be built first, do that a romance can begin, such as in Girl Friends, you know since it wasn't until the end of Vol 1 that Mari started feelings showed.
Guessing from the series plot outline, most likely the whole relationship will develop once we have the whole training part is done.
As for the actual manga itself, I find the art to be the weakest, feels like the mangaka's art style isn't formerly complete yet, so might be fun to watch it improve.
