好きだった幼馴染に告白されたが嘘告だった日、ヤケクソになって一人公園で遊んでいる幼女と一緒に遊んであげたらその幼女が同じ学校の天使様の妹だった

Hanazawa Yuzu liked his childhood friend, so he immediately said yes, but it was a fake confession due to a punishment game. On the way home that day, while walking dejectedly and sighing on a park bench, he saw a five-year-old girl playing alone in the sand. There was no family around. Seeing that scene, Yuzu felt lonely and decided to play with the girl. However, that girl was actually the younger sister of Amase Kotomi, who was known as an angel at school. This event led Yuzu and Kotomi to become closer. This is a story about unknowingly and gradually entering the angel’s embrace and being enveloped in warmth.
