Long ago, I got into a manga called ‘Love Hina’. This is what one would call a ‘harem story’ where the male protagonist is eventually desired by all of the female ones. That has nothing to do with this post. Sort of. So, why did I bring it up?
The male lead is driven to get into a prestigious university because he made a childhood promise with a girl that they would reunite there. He’s not very bright, so he keeps failing the entrance exam. Yet, he refuses to give up. The issue is that he does not remember what the girl looks like. Oops.
I began thinking about ‘Love Hina’ when I watched ‘Kenichi: The Mightiest Disciple’ and a childhood promise turned up again. Kenichi had forgotten about the girl and the promise entirely. He still had a keepsake from it. This plot point didn’t show up until way into the second season when the main villain appeared. Childhood friend turned enemy because of the mysterious promise. For some reason, I think there were two promises or the bad guy misremembered stuff. Either way, I was again facing a story where the main character forgets a childhood promise.
What is with this plot hook?
I can’t really figure out why this happens so much, especially in anime and manga. I took a look and this tends to fall under ‘forgotten first meeting’ tropes. This is a revelation later in a series where you find that characters have already met. It’s usually rather strange because you’re led to believe they have never interacted prior to the story. Explanations for this range from mindwiping, memories fading over time, a long separation, not recognizing each other, or simply ignoring the timeline issue. This is why many readers can perceive this as a plot hole and why authors might add a childhood promise to the scenario. At least the promise connects it to the plot.
There was always an issue that I had with this forgotten promise trope. Using ‘Love Hina’ as an example, I think it was that you could only have the issue go on for so long. The male lead had this promise quest from the beginning, which got old at one point. Once you realized the truth, it got fairly frustrating that he wasn’t figuring it out. He did figure it out before the end of the 14 volumes, but then you had the extra issue of the main mystery being solved. So, things dragged a bit regardless of the comedy, character development, and action. As soon as the promise was revealed and kept, a story kind of putters along in search of a conclusion.
Maybe I’m too harsh and critical of this plot twist. I did used to enjoy it, but I guess it doesn’t work now that I’m older. Still, it definitely has some interest for short-term plot points. That’s only if the audience already knows the answer. It can certainly work better for a long series if there aren’t any blatant clues as to who the childhood friend was or the promise isn’t known. You have a mystery on your hand, which older readers might be able to connect with. We all have memories that are faded and some of them have ghostly images of forgotten friends. So, that’s something you can go along with if you want to write this story and get a lot of mileage out of it.
