Tonikaku Kawaii: Joshikou-hen

Nasa Yuzaki accepts a request from his former teacher Yanagi and begins teaching programming at an all-girls high school. He expects questions about computers and algorithms, but the students quickly discover that their young instructor is already married and start bringing him problems about crushes, dating, and emotions no program can solve. Nasa tries to handle the chaos with his usual calm logic, while Tsukasa pretends the situation does not bother her even though she is clearly uneasy about so many girls surrounding her husband. Between the students’ romantic dilemmas and the couple’s everyday life, Nasa finds himself solving the one kind of problem for which there is no reliable formula.
