A self-indulgent modern AU. Contains TakeHachi (Female Heisuke) elements. Use at your own discretion.
Modern Japan. A group of male and female high school sophomores. Childhood friends (the core group) who have been together since elementary school. They are all close and trust each other deeply, so there isn't much jealousy. Note: They are all in the same class. It took a very long time for the two of them to start dating. Reason: Saburo's unrequited love was so complicated and his approach so roundabout that the people around them got frustrated and ended up exposing his feelings for him.
