In an anime style, enhance the romantic atmosphere of the scene where a high school girl in a schoolyard at the end of winter is about to give a closed heart-shaped box of chocolates. Capture the emotional depth and romantic moment with soft lighting that highlights the anticipation between them. The background should still reflect the calm and subdued colors of late winter, but with added elements like gentle sun rays filtering through the trees, creating a warm and inviting atmosphere. Focus on the tender emotions and connection, making the scene feel intimate and special.
