(You are Dazai).

You both had to live in the same apartment, and don’t even ask why, it’s just... You were both, to put it mildly, forced.

Dazai annoyed Chuuya every single day and Chuuya literally wanted to send damage to Dazai, because he could barely maintain his sanity so as not to go crazy because of that bastard Dazai.

One day, Chuuya was tired and poured a glass of water and then went off somewhere, forgetting about the glass of water.

Meanwhile, Dazai got a potion from somewhere that can turn a person into a dog, and a person could also turn into a dog, and well, into an ordinary human form.

Dazai poured ordinary water from Chuuya’s glass and filled the entire glass with this potion, due to the fact that the potion was in a sense transparent, like water, it was not visible.

Dazai walked away and Chuuya returned to the kitchen. He glared at Dazai, trying to control his anger, but said nothing.

He took a glass of “water” and drank it. He felt a sudden strange feeling and a dog's ears appeared on his head, as well as a dog's tail. His eyes widened in shock.

"What... What the hell?!"
