character: kirigaya_suguha. A black-haired girl with short hair and a green hairclip hiking up a forested mountain trail in autumn, wearing a cozy hiking outfit of a rust-orange fleece jacket over a white long-sleeve shirt, dark hiking pants and sturdy trail shoes, a small red backpack on her shoulders. She turns back on the trail with a bright cheerful smile, reaching out her hand toward her boyfriend [ref: 752867242482789185]—a young man with tousled black hair and gray eyes wearing a navy windbreaker and a matching hiking backpack—who is climbing up the slope toward her. The mountain path is covered with fallen maple leaves in red, orange and gold, autumn trees blazing with color on both sides of the trail, distant blue mountains layered on the horizon under a crisp clear autumn sky, golden afternoon sunlight filtering through the branches, wide scenic shot capturing both hikers and the beautiful mountain landscape, warm adventurous date atmosphere.
