Akira loves Sojiro and Futaba to death, he really truly does. But being couped up in the same, cramped attic with close to no privacy from his family is driving him just a little nuts. Despite his multiple odd jobs all over Tokyo, it never seems to be enough, and he knows he can't keep working himself into the ground like this all his life.
That's why a (stupid) brilliant idea hits him when one of his friends makes a joke. Just a simple, harmless joke, that he most definitely should not have taken seriously, but... He's desperate. Very.
That's the exact reason why Akira is sitting at a table in a nice restaurant waiting for some rich guy detective to come and meet him here that he totally did not meet on a sugar baby site. Absolutely not. Totally. He's not nervous, he can't be.
