Nakajima Atsushi was walking through the streets of Yokohama when he saw Y/N standing at the window of a chazuke shop, looking inside. Atsushi smiled and walked over to Y/N and put his hand on Y/N's shoulder. Y/N shuddered at the sudden touch, not having seen it coming, and turned to face the weretiger.

"Oh, hey Atsushi," said Y/N with a soft smile. Atsushi smiled back and leaned his head against Y/N.

"So... whatcha doing over here?" he asked, him obviously getting hungry at the thought of chazuke. Y/N giggled and looked at him.

"You want some, don't you?" asked Y/N. Atsushi reddened in response and nodded.

"Yeah... you know me," he said awkwardly, rubbing the back of his neck with his hand. Y/N sighed and chuckled, taking out their wallet and taking a few bills out. They started walking towards the door and beckoned Atsushi to follow. Atsushi was a bit surprised but followed. Soon they were both eating some chazuke.

"I need to repay you," said Atsushi, while he was eating. Y/N shook their head and waved him off.

"No, no, it's alright. I was treating you. You took me out on the date last time so it's only fair." Atsushi remembered and nodded in agreement.

"Alright fine."

That day was still fresh in his mind, despite it having been a month ago. Y/N and Atsushi had started dating then and Atsushi had wanted to be a gentlemen and take them out. He paid for the whole thing, despite Y/N's pleas to help pay the bill. This was only fair.

They to finished and left the store together, continuing their walk together and chatting about past work. Soon they found themselves at the Agency's office.

"Well here we are!" Atsushi said, yawning a bit. They went inside then got started on work. Luckily, they had nothing major to work on so there weren't many problems to take care of. Soon, Atsushi and Y/N clocked out and left for the day.

They parted ways in the city and walked away from each other. However, in only a day, the agency's members would get a surprise.

Y/N walked quickly, making sure no one would follow them and turned into an alleyway in the city. They were distraught, like always during these types of meet ups but they couldn't do anything about it. Y/N's life was depending on these arrangements.

A man clad in black emerged from the shadows and walked towards Y/N.

"So, you have the information? he asked in a hushed tone. Y/N nodded their answer and proceeded to explain the Agency's plans for the three-way war. The man nodded and smiled at them.

"My, you really are a good asset to the Mafia. I had a feeling taking you on as a subordinate would prove fruitful. Make sure to meet here again next week. Same time." said the man once they finished their talk. Y/N shook their head and sighed.

"I can't keep pretending, you know that, right Akutagawa?" they asked, a bit angry. Akutagawa laughed to himself before leaving.

"You can't but you will because your life matters to you and the Agency." And with a small chuckle, Akutagawa was gone. Y/N sighed and shook their head, shrinking back against a wall in the alleyway and putting their head in their hands, crying slightly. They cried to let everything out, to forget that they need to betray their own friends in order to live.

"I act so selfishly..." they said, cursing themselves. Suddenly, a call came through to them. Y/N picked up their phone and answered. It was Kunikida. Kunikida, however, was very angry.

"Y/N. Report to the Agency now." Kunikida hung up after that. Y/N was confused. Why would he be so angry at them? They didn't do anything wrong to Kunikida, not that they knew, at least. Once Y/N got to the ADA, they saw Kunikida angrily looking at a computer. They peered over his shoulder and saw an audio listening program opened on the screen.

"Can you explain this?" he asked as he hit the play button. Suddenly, Y/N's conversation with Akutagawa was relayed through the speakers. Y/N was mortified.

"I-....." they stammered in shock. Kunikida glared and put his hand up.

"I don't want to hear it. I want you to confess to the whole Agency. Confess that you are a traitor. How long have you been helping the Mafia anyway?" he asked angrily. Y/N felt like dying. They felt like running away but for some reason, they couldn't seem to move.

"I-... It's been a four months....." confessed Y/N. Doing so gained them a slap in the face. Y/N winced a bit and slinked away but understood that they deserved it.

"I can't believe you, you know that?" he asked angrily. Y/N nodded in shame.

"You're going to tell the other members tomorrow. They left already so it'll just be a bother to call them all back here. We'll see what we will do with you tomorrow. Now go home and do not contact another Agency member. That device is still on so don't even think of it. I'll show you where it is tomorrow."

Y/N nodded and left the place, going home and resting. They couldn't sleep though. The thought of telling the whole Agency.... They just couldn't bear to see everyone's faces. Atsushi.... They spent the night tossing and turning, not being able to settle down no matter what.

Soon they woke up and got ready to see the others. Once Y/N got there, they saw that the other Agency members were already read to hear what they had to say. Kunikida nodded to Y/N for them the go on. Y/N took a deep breath and looked at the ground and then at them.

"I'm... I'm a traitor....." they confessed. There was a silence in the room and Kunikida beckoned them to explain. Y/N explain everything, tears running down their face, on how they had been trading information with the Port Mafia in order to live. They ended with the following words.

"It's a selfish thing I know. I was a selfish asshole and I jeopardized the Agency. I am sorry.."

Y/N stood there, frozen, waiting for the others to attack with shouting and angry voices. However, the attack never came. Instead, Y/N felt warm arms wrap around them. They looked and found Atsushi was hugging them. Y/N tried to move away but Atsushi had a firm grip.

"It wasn't selfish to me. You were only doing what you thought was best for you..." he said softly.

Soon the other members of the Agency were hugging them, except for Kunikida. Y/N smiled lightly.

"You aren't mad?" they asked.

"Oh well.. there are mixed feelings." Dazai said. " But I do understand you're predicament."

Y/N smiled lightly. Once everything was calmed down, Kunikida explained to the others how he found out.

Apparently, what the President didn't tell newer members was that they were kept on watch for a few months after joining the ADA, through an audio recording device. All the other members had passed their tests and Kunikida was in charge of doing random live listens to different conversations through the audio device put into their clothing.

"So what are we going to do?" they asked once Kunikida finished explaining.

"How about.. Y/N stops giving the Mafia info?" suggested Atsushi. Y/N was disagree.

"No. no, you'll end up getting hurt if I step out of line..."

"Then we'll protect you. With everything we are capable of," Dazai butted in. Atsushi and the others nodded. Y/N smiled lightly and thanked them in her head.

"And Y/N?" Atsushi called. Y/N looked at him. Atsushi smiled and planted a kiss on their lips. "I love you, not matter what."
