I think tattoo body guy is lonely and seeing black hairs gentleness makes him jealous wanting to unravel what dark hair is hiding I think he has a hero complex or just likes being needed. Meanwhile tat bod what's to be needed and get in return I think in the end either they are going to lose the third wheel and get together after a series of trials and then eventually balance each other out or maybe just come to the realization of what they actually what.
That brat needs to be punished for trying to kill.
