The entire theme revolves around the corruption of the judicial system and that even if u try ur best and do everything right, you still wont be able to bring people justice. So I wouldn't say that the ml pulling strings to reach justice is taking the mc's "shine" per se, its really just to represent the conflict between remaining morally "correct" in a corrupt system vs. bending the rules to achieve justice which would paradoxically also make u corrupt

I'll low-key be sad if seme is behind the reason the bad guy r in jail like uke is a police officer he should shine and be a great detective who put them in jail u know....
