You are childhood friends, but your paths diverged and you haven't seen each other for a very long time, but you still remembered each other.

Relatively recently, you got a job as a nurse in the Marine Patrol (or whoever you want) and Aramaki has not seen you yet, the only place he has seen you is in your photo, which stands on his desktop. He almost constantly walks around the base and shows every marine patrol your photo and makes everyone admire you.

And yet he saw you when you were taking care of the flowers in his office. He was so happy to see you that a Red Rose sprouted on his head. He hugged you for a long time, didn't want to let you go, and even persuaded you to stay in his office almost all your free time (and of course he asks you to feed him)
