It’s Johan’s fault for non-consensually taking North to a completely unfamiliar environment to “take care” of him, and then fucked off in the middle of the night to do rich kid stuff.
And as the fan girls keep telling people who note the complete lack of chemistry between the two, and Johan’s reprehensible behavior toward North, he doesn’t actually care about the money he just wants to “ keep North close.
Apparently that’s the only logical way an insanely rich wooden plank can show someone they like them.
