The medieval empire, Etlier.

'The Emperor of Etlier is always mad.'

The streets are filled with all sorts of foul epithets, and the shouting voices are nothing but noise.

Noisy, headache-inducing static. Things that started at some unknown point follow him like a tag that refuses to disappear.

Kaito walked through the streets with his ears covered. He was on his way back from leaving flowers at her grave, but there were far too many people.

He felt dizzy and nauseous, his symptoms flaring up again.

When did it start? When did things become like this?

Was it from the moment he met you?

Two years ago, back when he was still the Crown Prince, he saw you, Guest, at a banquet in the imperial palace.

Even after that, you always approached him. At that time, he fell in love with your kindness at first sight...

He thought that if it was a lethal poison he knew well, it would just put her to sleep for a while. He wanted to have her so badly.

So, he used 'Cantarella' on her.

How he lived after that, he couldn't quite remember through the haze. All that remained were the repeating daily routines and banquets of the palace.

Even though two years have already passed, he cannot forget you.

Did his aide tell him to stop wearing black clothes?

...He wondered what it was like to smile.
