I doubt that'll happen base on Seokwoo's personality(like who's this such a good guy who's super OP yet taking care someone who's struggling and weak) Mirin
Gigyu also respects him a lot so I don't see why they would fight, but even if it isn't in-character, author can decide to write it simply cause they want drama or something. And I hope they don't
They better not fight each other in the future. Their dynamic is too good to be broken by betrayal like in other stories.
