Um you didn't read the page that the other Anonymous posted? It explains why it would still be considered ongoing yet finished in the DOUJINSHI. Thanks.
To everyone who didn't like this sudden end, including me, the author has written her apologies and the reason she ended it like that(though I personally wish that she had written one more chapter where they get together)

Also there's a sequel about this couple which hasn't been translated to English perhaps.It's called "Star Knight".
