This pair can indeed be written into a novel's plot.

Basically, when B was still a poor kid, he desperately licked A, but his poor character ended up angering A. A, as a big shot who made money early in the industry, saw B as someone he could summon or dismiss at will.

A probably never expected B to be so skilled 👅. Gradually, with some insider information and deals, B also climbed into the ranks of successful people. Although his wealth is still far behind A's, he no longer fears A. So recently, they've started to clash again...
