Tsundere-like boy has a beautiful and popular childhood friend chasing after him. She may or may not have yandere potential. Seemed like a cute setup, except the guy has 0 romantic feelings for her. Romance stories where one has to chase another who has no feelings for them, isn't as enjoyable as one with at least some chemistry between the prospective couple as a starting point. He treats her like an annoying sister here (TBF his attitude is what many real-life childhood friends are like, and why it often doesn't work well IRL).
6 years later and there is no serialization, so that means this pilot oneshot failed to get enough support from fans to convince the publisher in the merits of a series.

No idea why they refused to translate that. I don't think it's a "Keikaku" means "Plan" kind of meme; it's just next level weebery to keep those in (I only forgive keeping honorifics, which don't always have a direct English translation).
