Let's go through some basic knowledge before I talk about it further...

Characters: Brock, Nurse Joy & Officer Jenny
Canonical?: Semi-canon
Relationship status: Acquaintances/Friends/Feelings on Brock's side
Also known as: TakeJoyJun

What do I think?:

I like this ship!
I could definitely see Brock being in a poly relationship anyway because he wouldn't be able to pick just one girlfriend
So yeah, pretty good

I shall rate this ship: 8.5/10

Thanks for reading, see you in the next chapter!!!
