Here’s an overview of the game, via MangaDex:
Inept at dealing with people, Hikawa Koyuki maintains a wall between herself and others. She spends her time in highschool away from others, all alone. At least until she encounters Amamiya Minato who keeps closing the distance between them for some reason?! The aloof Koyuki, the popular Miki, the boundary-less Minato, and the easygoing and kind basketball team member, Youta. This is the story of these somewhat complicated four, and their tantalizing, bumbling youth! In its original webtoon form!
Agasawa’s You and I Are Polar Opposites manga received an anime adaptation on January 11, and Crunchyroll is streaming it with an English dub.
