I know it’s silly, but one thing I found refreshing about this manga is the fact that the MC doesn’t hide his power. First, he openly revealed his ability to all the girls in his harem right from the start, and now, instead of playing coy or trying to keep it a secret, he’s already made it known to the whole world that he has an overpowered ability.
As for the villain’s entrance, it felt very much like a “cartoonish villain” move. I believe that, in the real world, if something like this happened, the parents would call their daughter in and calmly explain the reason behind their decision. But no—this villain bursts into the room and, with an “evil” glare, delivers the bad news to the heroine without a shred of care.
