Misute♡naide Daisy

Raised by his grandfather in a nuclear shelter, the brilliant Reijiro knows far more about inventions than other people. His plan to watch humanity destroy itself changes when he catches sight of schoolgirl Hitomi Matsuzawa and falls for her immediately.

Calling her Daisy without her consent, he resolves to make her part of his world. His inability to understand ordinary boundaries turns Hitomi’s school life into a succession of unsettling complications driven by genius and social isolation.
