First of all, the anime should've chosen either the key and lock or the arranged marriage plot device. Doing both just made the whole story clunky. Second, It would've been better if it was just a love triangle between Raku, Chitoge, and Marika instead of a harem. Both Chitoge and Marika were strong-willed, stubborn, and refuse to accept defeat. So them aggressively competing with dense-as-hell Raku in the middle of the chaos would've been more fun and compelling to watch. I'd also want Marika to be the childhood friend with the key to the lock instead of Onodera. I don't hate her; I just found her boring compared to all the other love interests. Every joke and subplot that revolved around Onodera was the same, and her constant failed confessions were repetitive and annoying. Plus, she really had nothing going for her in the harem apart from being nice, pretty, and Raku's childhood friend. What made Marika's love for Raku more interesting was that her dad was the police commissioner. Imagine how interesting it would've been to have a love triangle with the daughter of a gang leader and the daughter of the police commissioner. The story's overarching conflict could've been Raku choosing between uniting the two rival gangs or creating peace between his father's gang and the police department. Overall the story was fine. If you like harems, you'll like this. I just wish the story were better.
