In an anime style, depict a high school girl in a schoolyard at the end of winter, holding a closed heart-shaped box of chocolates. The box is clearly closed, emphasizing the moment of anticipation before it's given. She's wearing a traditional Japanese school uniform (seifuku) with a blushing expression, indicating nervousness and excitement. The background features the calm and subdued colors of late winter, with bare trees and a distant view of the school building, capturing the transition from winter to spring. The focus is on the closed box and the girl's emotional expression, reflecting the quiet, hopeful atmosphere.
