So, fun fact, Ohime-sama in japenese basically translates to “princess”, so Ronaldo is calling Jane his princess, which is adorable. Tbh, their ship is as good, if not better than Lars and Sadie’s ship.
What if Steven and Connie are already dating and they are just hiding it? Like in Regular Show with Rigby and Eileen. Maybe that's why Steven didn't deny that Connie is his girlfriend when Ronaldo told him. You know, Steven never lies, but he can avoid telling the truth :^)
