Watermelon, Baseball Bats, and Me, Stranded on the Beach

As a lifelong bachelor, Sato Kumajima believes that only people who live alone have any real significance. True love and marriage, being such a waste of time and money, would never make it onto his messy list of life goals. Of course, that doesn't mean he slipped through compulsory education unnoticed. On the contrary, his twelve years of schooling plus four years of college before being reborn have become his greatest support since his rebirth. Then, one April in his first year of high school, he walked into a strange club and met the mysterious girls there. For the first time, Kumajima lost his composure... That was the blurb. To reiterate, this is simply a rebirth story, set in Japan, with no System. Please don't wander into the wrong book, dear readers.
