A detective who'll find your leading lady for 500 won has appeared! Out of all the countless web novel protagonists, I wasn't a romance-fantasy noble lady, a cool hunter, or a holy saintess. Of all things, to think I've been reincarnated as a 'private investigator'… And on top of that, my clients are all regretful male leads? "Hurry up and find my woman." "All of a sudden?" Still, now that I've started, I have no choice but to see it through. Just how many 'runaway lead' stories do you think I've read?! The runaway female lead always gets caught soon enough. They come back one way or another! The cool guy, the hero, the beastly man— I'll make sure all the regretful male leads get their happy ending.
