Taishi Tsutsui is the creator of We Never Learn (Bokutachi wa Benkyou ga Dekinai), a romantic comedy manga that ran in Weekly Shōnen Jump from 2017 to 2021. The series followed high school student Nariyuki Yuiga as he tutored three girls of genius — each brilliant in one subject but hopelessly weak in another. We Never Learn was notable for its unique ending structure: Tsutsui wrote five separate "true route" final chapters, each showing a different girl winning Nariyuki's heart. The series sold over 10 million copies worldwide.
