Catching up to the tiger

When fanboy Jae-Kyung enters his favourite web-novel after the 5th loop he drops in just before the OG-Male lead starts building a team that will be crucial in the long run so what were the chances of him being a support-type? clearly this is a divine intervention He has the knowlege as a transmigrator and a harcore level so why not help Beom and help change its crappy ending? who minds if he replaces the female lead in her role, he never liked her to begin with. He has the chance so why not catch up to Beom?
