💡 Detailed Explanation
The suffix '-的' (-teki) attaches to a noun to form a na-adjective, indicating the quality or nature of that noun. '計画的' (keikakuteki) means 'systematic' or 'methodical'. '～風' (-fuu) means 'in the style of' (e.g., サラリーマン風 - like a salaryman). '～流' (-ryuu) means 'in the way/method of' (e.g., 自己流 - one's own way). '～式' (-shiki) means 'style' or 'ceremony' (e.g., 日本式 - Japanese style). These do not fit the context.
