Ending

I just finished the novel

It has three parts, I only read the final part
I think the novel is too long so this manga while be axed probably at the ending of the first part.


The problem is this has an open ending even in the novel.
The main couple has a happy ending, a family.
But the supposed final evil boss gets away so other character goes for him, to uncover the motives for his evil acts, and that's the ending.
This needs a spinoff for that but the author said they don't plan to do that at least any soon
