MIB AU where Sousuke is a police officer chasing a criminal that turns out to be an alien. Because he's skilled he gets recruited by the Men in Black and ends up with Makoto as a partner. From then on they work together as Agent S&M.
na na na, come on, come on, I like it-like it
Imagine Agent S&M reporting for duty and Makoto’s embarrassed and suggests for the duo nickname to be changed, but Sousuke’s like “lmao no. this shit is hilarious, they’ll fear us before we even arrive. here let me bring a whip for show and they’ll be pissing their undercover generated pants.”
