Anime scene of a man and a woman looking at a bottle of water

anime character with dark yellow eyes and messy, medium-length dark hair pulled back. He wears a white scientist's coat over a white t-shirt and brown jeans. This character should exhibit a tired appearance, with noticeable dark circles under his eyes and wrinkles, reflecting the toll of insomnia and age. He's holding detailed chemical bottles. Pay close attention to the detailed eyes and lips with a sharp focus. The art style should resemble Demon Slayer, featuring pastel colors. Ensure it's a 4K masterpiece with realistic lighting and shadows, but we can leave out specific background elements like lab equipment, scattered papers.
