anything else? This isn't focusing on the cousin, friend or sister btw.
* Pigeon who wanted to start a revoloution in HS, went to and graduated from university, was always a constant in Bun's life and helps run the business with him.
Explains a lot.
There are just so many stories in both the "Are you enemy" and "Rules/Hydro" timelines. And they are not linear either.
So, Akio had a girlfriend who dumped him. Akio then had a sort of relationship with High school Bum. 18 year old Bum then both was a rent boy and raped by his boss, he then was in a sort of relationship with Daisuke. Daisuke previously was married and also had an affair with a high school girl. 20 something Bun then had a girlfriend, and a few more since "Not love". Bun then meets Akio again, but nothing rekindled. Akio's girlfriend from at least 10 years ago then enters the scene.
am sure there are lots more other romantic relationships missed out.
