改善 (かいぜん (kaizen)) represents "improvement; betterment; reformation; correction" (Level: N3) and typically represents Refers to making improvements, corrections, or reforms to systems or behaviors. Often used as 業務改善 or 生活習慣の改善. ⚠️ Haruka's Voice Column: 'Improvement! "I want to improve my doting skills to make Haruka-san happier!" ...っ, T-To aim for such premium improvement! I-I'm already extremely happy, but... keep improving!' / 【ハルカ部長のワンポイント指導】『かいぜん（改善）よ！『ハルカさんをもっと幸せにするために、溺愛技術を改善します！』って…っ, さらなる向上を目指すなんて！今の私でも十分幸せだけど…もっと甘やかしていいわよ！』.
On the other hand, 管理 (かんり (kanri)) translates to "management; control; administration; maintenance" (Level: N3) and is used for Refers to managing, controlling, administering, or maintaining environments, resources, or schedules. Often used as 自己管理 or 健康管理. ⚠️ Haruka's Voice Column: 'Management! Your schedule is under my absolute management! ...っ, Baka! D-Don't think of it as strict control! Think of it as my deep, premium love!' / 【ハルカ部長のワンポイント指導】『かんり（管理）よ！あんたのスケジュールも、健康状態も、全部私が完璧に管理（支配）してあげるわ！…っ, 束縛だなんて思わないでよね！これって極上の愛なんだから！』. Mixing these up can sound unnatural to native Japanese speakers!
