The Double Black Duo from Another World Keeps Dropping By

One day, Dazai met sixteen-year-old Chuuya, then watched him pull his own sixteen-year-old self out of the river.

Dazai: ???

Later, Dazai met another version of himself wearing a black suit and a red scarf. He also saw another Chuuya dressed in a black suit and red shirt.

Dazai: !!!

After that, he met lots of versions of himself and Chuuya. For example: himself holding a much smaller Chuuya, himself with Chuuya's name on him, Chuuya with his bite marks on his neck, and two tiny versions of them who called each other Chuchu and Osamu...

Dazai: ...

Why do you keep dropping by our world?!

Is showing off your love really that fun?!

Theme: No matter which world we're in, we love each other
