Damn, poor brave man who tried to stick to the legend when he realised Ririn connected the dots. And that is even after she had already kicked him once.
And her reaction. Huh, Delice owes her honest explanation now...
Since she turned her serious mode on, she was able to formulate her own theory why he was so thorough in getting her as wife. From pure logical perspective, that IS a good explanation. Obviously ignoring he was smitten by her. But hey, can we blame her for that?
And I doubt it is a yuri route because it is the same person who isekai'd her, no?
