Create a thumbnail that captures the essence of a heartfelt, nostalgic story

Create a thumbnail that captures the essence of a heartfelt, nostalgic story. The thumbnail should feature an elderly man with white hair and a gentle smile, holding an old book close to his chest. The background should be a cozy, small bookstore with warm lighting, filled with bookshelves. The title text "স্মৃতির পাতায় লুকানো ভালোবাসা" should be in elegant Bengali script, prominently displayed in the center. Use soft, warm colors to evoke a sense of nostalgia and deep emotional connection.
