Can you spoil me the ending?
Fred Clark's Law, "Sufficiently advanced incompetence is indistinguishable from malice."This isn't a defense of him but I think he is being genuine, he's just COMPLETELY emotionally illiterate to the point the usual common sense rules of basic social etiquette are a foreign language to him; he's not doing any of this out of malice but sheer ignorance. Basically he's a fucking dumbass.
You know, there is always the possibility that they pulled a reverse card on us. There's tons of manga that are teasers for novels out there, but this time maybe the novel is the teaser for the manga...It's really a "non-ending". After graduation, her interest in foreign languages has grown and she goes to study abroad. Her parents only agree if Keios goes with her. In his mind, he's there to keep someone else from stealing her. In her mind, he's there because her parents insist. They will marry upon returning home but she's still thinking white marriage and he is still trying to woo her. Arguably, a suitable fate for both of them. She's still happily alone and he is still paying for his mistakes.
Of course, we should keep in mind that, since they are fleshing the story out in the manga, so there's nothing to stop them from continuing after the WN's ending.
The girls being MVP especially the black haired girl that started as villainess.Love that the girls are all rallied behind Nicole.
The key point that they all understood is that, even though there were nothing untoward between the Keios and the princess, the neglect was still real.
And what Keios asked the girls to help him with? Props to the author for keeping him true to his character. He thought he could repair their relationship by love bombing her. Which, IRL, is also another red flag.
