今日から始める幼なじみ

Transfer student Kaede Yuzuki moves into the house next door to Kohei Aida and ends up seated beside him in class. Eager to befriend her, Kohei attempts to strike up conversations, but their exchanges often falter awkwardly. One day, Kaede pulls him aside with a serious request, proposing they start acting as childhood friends from that moment on. Confused yet intrigued, Kohei agrees to the unusual pact, leading them to navigate daily school life with forced familiarity. As they practice gestures and dialogues typical of long-time companions, subtle tensions and budding connections emerge between them. (Unreviewed summary by Grok 4)
