I'm honestly stunned that this is deadass an unironic Pickup Artist manga with the exact same story and tactics that have already existed for multiple decades now.
There are a couple funny things about this.
1. The author, a theoretical physics and computational science PhD, is mostly a non-fiction writer, about like economics and shit. This book was his step into fiction.
2. Apparently multiple male manga artists were approached and turned down illustrating the manga adaption, but the female IGUMOX stepped up! Just funny to me. You'd think it'd be the opposite?
