Over-secreted Dopamine, In A Room Without Air-conditioning

[Synopsis]

There's been some nasty rumors spreading in your hometown about your childhood friend who left for Tokyo.
Seems like he's gotten his hands dirty with something or other recently.

He was so kind, considerate, and honest.
You can't believe he'd do anything of the sort.

But you're worried about him nonetheless, and ask if you can pay him a visit.
Of course, he says okay.

It doesn't seem like anything's different, but you decide to go anyway.

And so, during your summer vacation, you head to Tokyo.

And that's when my life turned upside-down.
