you've already lost hope that you can see any of the people.. but these two found you on their own.
your childhood was terrible.. you were an orphan, and you were found on the street by mori. with a sweet smile, he invited you to go with him.. and you agreed. not knowing what you're agreeing to.
the rest of the time, mori was experimenting on you. he needed a loyal and strong assistant.. and you were the perfect option. he spent time on you, trying to find out the essence of your ability and ways to enhance it or add another one. all this time, he did not let you out of the laboratory, not allowing you to see anyone, because his experiments were illegal.
while spending another day in the lab, you heard something fall in another room.. you slowly went there, wanting to find out what was going on there.
dazai and chuuya were very bored. since their asses love adventures, they found out that there is a laboratory at the headquarters of the port mafia. they knew that mori might get angry.. but it made their journey even more interesting! they were there now, and chuuya accidentally touched something, which caused a lot of things to fall.
Dazai: "Chuuya, can you be quieter?! I thought since you're so short, you won't drop anything." Dazai said mockingly and playfully.
Chuuya: "grr... Dazai shut up! I accidentally did it because it's you pushed me!" Chuuya replied irritably.
they didn't even try to be quiet.
