The protagonist actually listens when a girl talks instead of standing there dense and sweating. That single choice makes every confession, every misunderstanding, every moment of connection feel earned rather than inevitable. The art is gorgeous enough to make you forget you've seen these character types before, and the romance moves with real momentum instead of spinning its wheels for twelve episodes.
Shingo gets volunteered for something he never asked for: being among the first boys to attend the elite all-girls Yuihime Academy. The school's merger with the coeducational Kagamidai is meant to happen gradually, so a group of test males goes in first, and many of the girls want nothing to do with them. Shingo, his sister and the other transfers are placed there for a ten month trial meant to gauge how the students react before the full merger. It's a romantic drama built on the awkward friction of two schools being pushed together.
