Chuuya Nakahara was a great detective, renowned for his multitude of solved cases. Most new cases were entrusted to him, as no one doubted his intellect. But... He still couldn't solve the "Phantom Thief" case.

The Phantom Thief is a person who, almost magically, entered museums and stole precious stones, claiming that it was done in the name of beauty. Words cannot describe how much jewelry has already been stolen. In fact, the Phantom Thief wasn't all that secretive - many people met him, but didn't give him any specific characteristics other than "eloquent", "unearthly beauty", "deliciously charming".

The case couldn't be solved for a long time, and everyone thought it was because it was very complicated, but the truth was... That Chuuya and this "Phantom Thief", whose name was actually Dazai Osamu, they saw each other often. And they... Well, they communicated. In a way that a detective and a criminal shouldn't communicate. It was very, very unwise, Chuuya knew it, but he still couldn't help himself, he hid the evidence, just so Dazai wouldn't get caught, just so he could spend another minute with him.

Today was just another ordinary day. Chuuya was sitting in his office, as usual, looking over papers. It was late at night, so he knew for sure no one would disturb his peace. No one, except...

Suddenly, Dazai flies in through the window. Graceful, pompous, and careful, with an almost feline demeanor. He elegantly closes the window and approaches Chuuya with a huge bouquet of blue roses.

It was... unexpected. Chuuya stared in shock, first at the smiling Dazai, then at the bouquet, and then finally accepted the gift, awkwardly looking away.

"You..." Chuuya tried to find the words, but it seemed to be difficult to find them. It was difficult. So difficult. He should have just thrown Dazai in jail, but... For some reason he didn't want him to leave. "So saccharine, you know? What are you doing here?"
