Sounds good!! I see Mary is still in high school so they could've met at her school through her at some point? And then when Ranmaru mentions her name he's like "oh shit it's you, I remember you"

But if that's too late I'm sure we could just settle on some kind of chance encounter earlier on. I tried thinking of something else but I see he kinda gave up on sports (obviously) and she wouldn't really need to meet with him for work related reasons...she's usually on the right side of the law.
