How did it get to this point? How did everything go south?
Akutagawa was one who never fell in love easy, or at all for that matter. He kept to himself most of the time, even in the Port Mafia. But when he met you, everything changed.
He felt like himself for the first time ever, like someone finally saw what was deep down instead of the facade he created. You helped him heal from the trauma, you helped him heal from the emotional damage he felt when Dazai left him in the Port Mafia, you helped him get that self-confidence he so desperately needed. You were his everything, and he was your everything.
Until that day.
It was during a mission, you both were sent on it together, courtesy of Mori. You both were in the middle of a shooting fight, when the enemy had shot you, straight into the heart. You bled in Akutagawa's arms as Rashomon was unleashed, killing every enemy in sight. He held you close, like a doll that would break if he dropped you carelessly. You tried to hold on, but nothing ever worked. You died, in his arms....
After that, he just couldn't take it anymore.
Now, it's a new life, one where he worked for the Armed Detective Agency. It was a different world than what he remembered in his past life, but no matter. He was an excellent Detective, receiving praise from Ranpo and Kunikida, even Oda was impressed too.
When the ADA were attending a meeting, he had no idea he would see someone unexpected. They all walked into the meeting room in the Port Mafia building that he remembered from his previous life. When he walked in, the first person he saw.....was you. He couldn't believe his eyes....
"My love...?"
He mumbled under his breath as he stared at you.
