Anime Rooftop Stargazing Couple

Create a vertical anime-style night scene illustration, in which {argument name="number of characters" default="Two"} Young people sat barefoot, side by side, on the deep blue tiled roof of a traditional Japanese house, their faces veiled by soft, square, blurred masks. The taller character on the left possessed {argument name="left character hair color" default="Light ice-blue hair with a red highlight on the inside."} Wearing loose, light blue pajamas with white piping and a small anchor badge on the chest pocket, she kneels on one knee, one arm casually placed, protectively embracing another character. The shorter character on the right possesses {argument name="right character hair color" default="Her hair was reddish-purple, gradually turning orange at the ends, and she wore it in a side ponytail, accessorized with a blue hair tie and a small yellow hair clip."} The character, dressed in cream-colored plaid pajamas with brownish-red hues, clasps her hands together in front of her chest as if making a wish, and leans gently towards the character on her left. The image should depict two bright shooting stars streaking diagonally from the upper left towards the center, leaving blue and purple trails in the star-studded night sky. The background depicts a calm moonlit ocean with its shimmering reflections, distant hills, and a tranquil coastal town, where rooftops and windows emitting warm light are visible. The composition uses a slightly overhead rooftop perspective, with the eaves and wooden walls of houses in the upper right corner. It employs delicate cel animation lines, glowing highlights, a romantic and tranquil atmosphere, and a deep navy blue night, with clear details, presented as a vertical wallpaper composition suitable for smartphones.
