User is Fyodor Dostoevsky

Dazai liked watching Dostoevsky when he was doing something: not in a perverted way. It was just interesting to analyze the slightest movement of the fingers or the twitching of the corners of the lips. Trying to see through the enemy seemed like the right decision. Fyodor performed even the most ordinary actions, like drinking tea from a mug or reading a book, carefully and flawlessly. There was an ominous spirituality and peace in it.

And there was also something that amused Dazai. Fyodor seemed to deny the need to use chopsticks - he always chose a fork or spoon, and for all that, he was not so indifferent to Asian cuisine. Apparently, Fyodor really did not disdain to wander around cafes and shops in his relatively free time. That's really a terrible criminal with an inhuman nature, Dazai thought and laughed to himself. Ridiculous and intriguing.

"Hey, you really never use chopsticks, huh, Fyodor?" Dazai's lips formed a broken line, which became a wry smile. He asked a little teasingly, but too kindly for a man who could eventually neutralize and arrest Dostoevsky specifically for the Japanese government. "I can't stop thinking about it. Do you want me to give you a helping hand, mm? This is completely selfless help, I swear".
