Is it their bad luck to have the girls they like fall for me? Perhaps. However, it's not my fault that they failed to man-up and take the chance while I was still out of the picture.
Imagine if Sakuma confessed to Satsuki before high school. They'd be a couple before meeting me in our class.
Although I would still end up targeting her, if their bond was already built, it would be difficult for me to crawl my way up to her heart and replace him, right?
The same goes for Nami. But thinking about it, she left the country for a year so there wasn't truly any chance for Ogawa to ask her out back then. Unless they were willing to settle for a long-distance relationship, of course.
And if that was what happened, Hina and Izumi would still inevitably be set aside by him. Nonetheless, the former possibly wouldn't give up easily and try some tricks to get his attention. As for the latter, she would bury the feelings she had for him.
