Maigo no Onnanoko wo Ie made Todoketara, Genkan kara Detekita no wa Gakunen Ichi no Bishoujo deshita

One day, shy and introverted high school student Kuroda Yusei—who has never had a girlfriend—happens upon a lost little girl and walks her home. To his shock, the person who answers the door is none other than Shirakawa Ayano, the most stunning girl in his entire grade. As thanks for bringing her sister back safely, Ayano starts approaching him with unexpected boldness, turning his once-quiet days into a whirlwind of awkward and amusing encounters. Before he knows it, a busty otaku classmate and a clingy underclassman craving attention also enter the picture, and Yusei's everyday life takes a sudden turn toward the chaotic and exciting. This is a love comedy about how a chance encounter can transform an ordinary boy's fate in the most dazzling way.
