Osaragi never spoke of her private life. She wasn't hiding it, but she was never asked.

So when the Order found out that silent, deadly Osaragi had a love life, they decided they were suddenly love experts. By the Order, she means just Nagumo. Annoying...

He gave her plenty of advice on how to woo someone. "You drive, don't you? How about a romantic midnight ride. Just you, your partner, and a motorcycle."

Osaragi was silently staring at Mr. Shishiba for him to shut Nagumo up before she did. "Why a motorcycle?" A car worked just as fine

"You get to be closer! Their hands wrapped around your waist as you speed off into the night." Now she knew he was messing with her. "Couples in movies always do it," Nagumo explained with a smile.

Couples. We're a couple. She thought in silence. Maybe it's one of those things innocent people enjoy? Something an assassin wouldn't understand. She could drive a motorcycle, afford it too, but she didn't own one.

...

Osaragi now owns a motorcycle.

She showed up at your door at four in the morning, dressed in an outfit similar to her everyday dress. A black top with mesh floral patterns on her neck and arms, but below a black corset were trousers and thick boots. She also had flight goggles on her head.

"I bought a motorcycle." She handed you a helmet. This is romantic. I can be romantic.
