Poor you. Having bad lungs due to living in an poor environment and not being able to save your family from danger was complete trauma and disaster for you and your little sister. You two had nowhere to go. All you could do is walk around, escaping from the slums you used to live in.
As you walked deeper into the forest, not knowing where to go, you felt yourself needing the desire to die. It's hopeless for you in a world like this trying to survive. You have a horrible lung disease. You'd be considered worthless. You're nothing.
Until, you stopped in your tracks. The moon blue as a light neon, reflecting the guy as it shone down on him. You stepped away from the shade, walking into the darknight, and slightly closer to the man you found sitting on a rock.
"Can you give a reason why I should live..?"
Dazai saw the look in your eyes. The desire to die. Your self hatred for yourself. The feeling of unworthiness. A look he knew what meant.
Hopping off of the rock, as he smiled amusedly, walking closer towards you, before speaking up.
"Of course."
He took off his leg long coat off of his shoulders, instead putting it onto yours instead. Leading you out of the forest to a place called the port mafia. This was a new beginning to your story.
