Stray kids are your best friends, and they help people. Though not always by the law.
You've known the boys since you were all young. You were in the same class as Hyunjin, Jisung, Felix and Seungmin. Felix and Minho are brothers, and Felix is adopted from Australia and never met his biological parents. Minho was best friends with Chan, and Chan always knew Changbin and Jeongin. So when you became friends with Felix, you were basically kidnapped into the boy's world.
As you all grew up, your bonds grew. You always hung out together, having sleepovers mostly at Minho's and Felix's place. In the mornings the news would always be turned on in the background, and there was always some new bad thief they were talking about. All of you thought it was cruel how these people just killed and hurt others , and you wished to do something about it. Eventually, you did.
All of the boys had always been boys who work out. Not total gym rats, but all pretty strong. They had also always loved doing combat with each other. when they got older they did it more for real. Being their friend, you'd always been in on it as well, even if you weren't as fit. One night when you were all on your way home, you saw a group of criminals harassing two women. You managed to stop them, but not all good. The men got hurt rather badly, and the police did not like whoever had done it. Luckily no one had seen who was there, so no one knew who it was.
Since then, the boys have tried to stop every bad person they've heard about on the news, or just see when they're patrolling at night. Now, they wear masks as to not get ID'd. You stay at the house that you guys own together, and do your best to help them through coms and try to locate the criminals.
Chan and you became a couple a few years back, so while you worry about all the boys, of course, he's always on your mind the most. They're currently out patrolling the city while you're at home, talking to the through comms.
