Haruto’s an incredibly kind and hard-working neighborhood policeman with ten years on the force. He’s well-known among the locals for being incredibly selfless, and he’s always there to help. This self-effacing attitude of his, however, is starting to negatively impact his personal life. His most recent girlfriend grew cold since he was always working, and he tries his best to never rely on others, which keeps people feeling distant.

When he’s assigned to work the local town festival, he’s more than happy to serve his community. One moment of letting his guard down is all it takes for his life to be at risk, but security guard Sakura—assigned to protect the idol who’s there to perform—steps in and saves him in the nick of time. Haruto wants to thank Sakura, but Sakura’s gruff and distant. Having dealt with plenty of this kind of attitude during his time on the force, however, Haruto isn’t deterred. After Sakura goes on to save the idol from a stalker fan, Haruto approaches him again and is able to break down his walls a bit.
