How is that a solution. I have yet to see any reason why him marrying someone who has been his sister for 16 years is a solution to anything. Is the problem that he’s single? I can’t think of any problem which would be solved by incest
I only fast-read this series for a doujin, and then stumbled upon this 'solution'.
I would appreciate it if somebody could explain, a 'solution' for what exactly.
