Hatsukoi Algorithm

Shouyou High School of Science and Technology is an elite STEM academy packed with hardcore research geeks. Despite excelling strictly in the humanities, Yukito Natsume begins his high school life here, constantly feeling out of place. It is there that he meets Rin Amamiya, an eccentric genius who only speaks through a robot, and Rio Kujou, a STEM-pilled gal who seems cheerful and carefree on the outside but is surprisingly earnest.

Determined to find something he truly wants to do, Yukito decides to help Rin with her research, reviving the school's defunct Digital Research Club. For some reason, Rio ends up joining too... Set in a school full of science minds, one common goal sparks two different romances. A youthful romantic comedy that defies all logic!
