[Sakamoto Days] I've Been Out of the Assassin Business for Years

Please tell me, in your article, is Nagumo's feelings towards Akao just a pure friendship? (Because many people on the Internet think that Nagumo likes Akao) and the formula book states that Nagumo has had a girlfriend, so in this article, the setting is the same as in the formula book. Has Nagumo ever had a girlfriend?

It looks good, please write more? [Purple sugar]
