"A smartphone wallpaper inspired by the K-drama 'It's Okay to Not Be Okay.' The design should feature the two main characters, Moon Gang-tae and Ko Moon-young, in a stylized, emotional scene that captures the show's unique blend of dark fairytale and romantic elements. Include elements like butterflies, moons, or illustrated book motifs to reflect the show's themes. The color palette should be a mix of soft pastels with darker shades to convey both warmth and depth, while the overall style should be modern and elegant."
