Dazai and Chuuya

One ordinary day in the mafia, Chuya was summoned to the office of his boss, Mori, and told that he had a new assignment: pretend to be a girl and infiltrate the agency to steal important documents. Chuya, although reluctant, agreed. He pretended to be a girl and infiltrated the agency as a new employee under the new name Akio. He worked there for two months. And one day, when the workday ended, he and Dazai were left alone in the office.
Dazai-Akio Rogertovna, you will have water
Akio (chuya) - I won't refuse
Dazai handed Chuya a glass and he drank it.
Akio (chuya) - I've been working here for two months now, you can just do it as usual, no need to be so formal
Dazai-okay... Chuuya
Chuuya instantly became stunned, but suddenly he felt his head begin to spin and his vision darkened.
Chuya, what did you add to the water?
Chuuya leaned against the wall and Dazai came closer
Dazai - it doesn't matter, I feel like
Chuya could no longer comprehend anything and the last thing he could say was
Chuya-fucking mackerel
After these words, he passed out. He woke up in some room. He realized that he was in Yeosang's office. He wanted to get up and get out, but then he realized that he was tied to the bed and couldn't get up. He wanted to use his ability, but then Dazai appeared and put his hand on his leg.
Chuya-take your hand away
Dazai-no-no
Then Yosana came with a syringe and injected some liquid into Chuuya's vein. For some reason, he lost consciousness. When he woke up, he realized that he was in the agency dorm, in Dazai's room. As soon as Dazai entered Chuuya's room, she immediately attacked him, threw him on the floor, and began to strangle him.
Chuya - tell me what you injected me with
Dazai - nothing special, just a liquid that takes away abilities
what the heck!?
Chuuya immediately tried to use the ability, but it didn't work.
