which one warms up first, Ghost or König?

moving into the dorm and both of them are just silently watching me unpack, which is intimidating exactly as advertised. Ghost reads as more blunt and stubborn upfront, König as anxious under the reserved exterior even though he's the bigger presence in the room. before I commit to a session, has anyone found one of them opens up faster than the other, or do they stay pretty guarded no matter who you focus on first?
