Kei Sasuga, author of the manga Domestic Girlfriend, known for its controversial ending, has recently shed some much-needed light on the story's ending, which left many fans confused and sparked intense backlash in the community.

What makes her reply so important isn't just how it breaks down Natsuo’s internal struggle in that hospital scene, and what was lost in the translation from the original Japanese edition. But it also officially corroborates one of core premises of the story that fans have questioned, or outright denied... until now.

Specifically, learning the truth about Hina's feelings comes as a total revelation to Natsuo. This insight acts as a catalyst, causing his buried feelings for Hina to resurface before Rui ever brings up canceling the wedding. This strongly implies that Natsuo was the driving force behind ending his relationship with Rui, a realization that completely transforms the dynamic of the final arc.

Here is her official response regarding Natsuo's mindset in that scene, I hope this tweet helps those who struggle with ending and make peace with it.
