The good thing about Braun is ur unlikely to perceive him as kse's friend, J3 is too quiet and talks too slowly for bsh to get a handle on their relationship, he's also powerful so kse is unlikely to be in a situation where he's risking his life for him.
Bsh's biggest threat is hyunmu team 1, I mean look at these guys.
A big strong guy, huge tits, sad eyes. Honest, dependable, morally upright. Very obviously YEARNS for kse, keeps saying things like "you can make a new home here with us" will probably be very direct about saying bsh is a BAD, UNTRUSTWORTHY, person and that kse should stay away from him.
And a suave, older gentleman who smiles too much, puts his hands all over kse without hesitation, is clearly very rugged and cool, kse is always looking at him with big bug eyes.
If these guys show up it's over for him.
