I've read this before in 2017 and that time i also realize after reading it for nth times that it is implied S.M, based on how kusakabe refer himself as the master and loves to see misato cry, begging and say please to him. Also misato himself talk about pain and such, its also leading him towards 'unusual' sex preference, thats why kusakabe said "you like it more if its painful, right?"
Its not just a simple "oh he's the seme" or "he's the uke". its bcs that's their nature. Those who don't like misato being the bottom should read more and understand their character, also misato is cute wdym (=・ω・=)
