Since page 9-10 were left untranslated... It seems like next chapter there will be a tournament? Natori says she will grant the winner any wish, and Diana says if she wins Lapis has to give Natalie-san to her. Is that right more or less?
Other people have commented but just to firm it up, that is what those pages are saying, and probably more or less a gist of what the next arc is apparently about (probably snippets of panels from ch18 sent to the publisher for specifically this preview section).
The fact the author is talking about the two main love interests in their future is obviously a reliable sign this is gonna be a poly route surely theres definitely no other reasonable explanation for it :copium:
