its a specific title, so i will try to jot down everything that I remember So the mc is engaged to the fl, but she really doesnt like him for some reason. To try and win her heart, he becomes like a servant to her, and thats for like the first few chapters but then, something happened and its revealed that the mc is actually the leader of some sort of underground crime organization and is called "the sage" or something by the people who know who he is and yeah the premise is really weird but that was all that i could recall and another note, fl was really rude to mc at the beginning, like not even tsundere type but just no interest then stuff happened and romance began
