How Could Boss Dazai Be Like This?

This is more or less a side story to Why Is My Older Brother Dazai Like That?

You can read the body-swap extra from Older Brother first, then read this.

He is Boss Dazai. Among the different Dazais in parallel worlds,

his life could certainly be called tragic.

One day, for no apparent reason, he swapped places with another version of himself from a different world,

and saw just how well a Dazai favored by his world's will could live:

that version had an angel of a girlfriend, Saeko, who had once saved the entire Oda family.

It would be impossible not to feel at least a little envious. But once the swap ended, he wasn't going to search the whole world

for the woman who might belong to him.

He hadn't planned on looking for her,

but his other self had already found her for him during the swap

only, she had been shrunk down.

Boss Dazai, who had felt a flicker of hope only to have it snuffed out at once: ...

Little Sa: ?

*The heroine was frozen, so she looks nearly ten years younger than Boss Dazai. She's a cool-faced girl with a rich inner life and slightly scattered thoughts.

*I got the urge to write this Boss Dazai IF side story for Older Brother. It'll be a few chapters at most.

*The worldbuilding is entirely my own, and this is my take on Dazai. To each their own.

Premise: I'll be here with you.
