From Yen Press:
High school is a fresh start for most people but not for Maki Maehara. He’s always been a loner, and he knows this year isn’t going to be any different. As expected, Maehara sees no change even six months in until he runs into his classmate Umi Asanagi at a video store! Always at the center of attention and ranked the second-prettiest girl in class by the boys, Asanagi is from a totally different world. But it turns out the two have some things in common, and not just the B movies they came to rent. When they become friends in secret, Maehara discovers his days are about to get a little more colorful! https://www.cmoa.jp/title/262343/
