Ketsuekigata-kun!

Are all A Types kind yet indecisive? Does being a B Type imply the opposite? Are O Types more passionate and childish than others? How would one even get along with AB Types? Ketsuekigata-kun! explores Japanese and Korean cultural stereotypes associated with blood types in romantic and leisurely situations. The anime adapted from the manga remake version of the Korean webtoon "A Simple Thinking about Bloodtypes" involving the faceless and nameless characters of four different blood types to discuss about popular anthropomorphized blood types (the stereotypes about the blood types) in Japan and Korea.
