What I mean is that each story follows the same pattern. MC's show off their skills, arrive at the boss, boss much stronger than anything they have faced until now, they barely manage to beat them thanks to some quick thinking.
It starts off really well. The main character flirting with the villainess was cute, and there was some nice tension between the characters. It gets a little stale halfway through though. The flirting the MC does with his fiancee never really changes nor were there too many pink moments in the later half, so the romance fell off. More than anything, most of the characters really just end up as side characters once their role is done. Once one of the conquer targets becomes a problem, the main characters deals with the problem, and then you never hear from them again. I loved the butler though, and I never got tired from him. I'd reread this whole story just for him.
