This reminds me of those old cheap detective stories where the jaded private investigator meets a beauty, solves her problem, and (usually) gets lucky with her along the way.
Only the PI is a high school girl, and the detective work is done offscreen by other people, so you just see a girl saving other girls at lightning speeds and gathering a yuri harem.
I can't help but feel it would benefit by longer (more than one chapter) arcs so the author could introduce and develop the characters and their problems more, show how the MC figures out how to solve the problem, and then even dedicate a little more time to the yuri fanservice. It's just a little unsatisfying how everything passes by so fast.
