Sometimes Kong feels "weird" around his new gang in Blackflame. It isn't because they bully him or are cold to him or make him do the heavy job, in fact, it is the opposite they treat him well, search for him to hang out and ask for his feedback to improve their performance.

The reason why he feels weird is because it is the first time that he is surrounded by people that actually love him or don't see him as a pain in the ass. He doesn't know how to react to all these good vibes.
