You think, yes, now I know what will happen next, now I know how it will end -- and no, you probably don't. While it was always clear that Trillion Game would win in the end, the "how" was very much not clear. I thought I'd know how Haru would do it, but, as it turned out, I didn't. Even at the last scene, there was a bit of a twist.

That said, the obstacles were overcome a bit too easily; and even now, I'm not clear about Princess Kiriri's motivations at times. I'd have liked to see maybe one or two fewer obstacles but better ones, or at least I'd have liked to see Haru having a bit more trouble in succeeding. As it was, his plans were a bit *too* perfect. More attention to details would have been a benefit to the story.

Speaking of details, one aspect that continuously irked me: The way that the actual *doing* was just disregarded.
For example, the opening of an e-commerce flower delivery: Where do you get the flowers from? Who will do the actual arrangements, even if they are planned by an "AI"?
Oh, and "AI", as Haru said himself: "It's a buzzword." Even if you can program an AI to do the things it does in this series, the costs for building and maintaining servers with enough processing power are enormous! Not only the material cost, but also the energy cost needed.It's why any company investing in AI has not seen a penny of return investment and it's expected to remain that way in the forseeable future.
It's a shame that the series doesn't pay attention to this sort of details.

Another aspect I found disappointing was the writing of the female characters. Yes, it's the story of the journey of Haru and Gaku -- but as the third partner Rinrin deserved better than to be used as scapegoat (even if she got her own happy ending), and that Princess Kiriri had to submit was also disappointing (even if it was for character-appropriate reasons). I would have liked to see them both put on a more equal footing with the men.

What I really loved though, and what made everything I just said insignificant overall, was the excellent acting -- by all of the cast. Meguro, of course, as the inscrutable Haru -- and until the last show-down I wasn't quite sure what exactly went in in his head -- but also Imada with her cool and calculating presence as well as Sano's depiction of an awkward nerd. I could list all of the actors, but then this will get too long.

Another plus in my book, there's only a hint of romance towards the very end, and even the sizzling chemistry between Haru and Kiri is always turned into rivalry, never romance.

The actors, together with the outstanding music choices and the fast-paced editing made the drama a wild ride, and I was hooked from the first to the last minute.
