부모님의 과잉보호를 받으며 자라온 주인공이 정반대의 남자와 만나며 새롭게 성장해 가는 모습을 그린 드라마

College student Kahoko is the quintessential overprotected child born out of today's Japanese society. Shielded by her parents, Kahoko grew up completely pampered and became somewhat of a miraculously naive "test tube human." She is 21 years old and about to start working for a company, but she has never slept away from home, had a part time job, chosen her own clothes, or even ridden a train alone. Kahoko has had her picture taken, but she has never taken a picture herself.

Now, Kahoko is about to step out of her germ-free isolation pod and into the germ-infested world. It won't be long until she realizes, "I'm different from everybody else!"

She has been her mother's best friend all her life and her father can't live without her. As they become emotionally unstable from the changes that Kahoko goes through, their family begins to fall apart. That's when Kahoko herself and the people around her begin to see the strength that hides deep within.

この物語は、現代の日本が生んだ【過保護の象徴】のような女子大生･カホコが主人公。何から何まで親の庇護のもと、温々と生きてきた“奇跡の純粋培養人間”就職間際の21歳にして、アルバイトもしたことがない。一人で服を選べない。送迎付きで駅まで歩いた事がない。そんな、ないない尽くしのカホコがついに、抗菌のビニールハウスから、雑菌まみれの世の中に飛び込んでいきます。そして一人の青年に告げられるのです。「お前みたいな過保護が日本をダメにするんだ」カホコの「自分探し」が始まり、毎回「こんなの初めて!」な経験を通して自分の中に眠っていた本当の“力”が、家族の問題を次々と解決していく痛快ホームドラマを目指します。

Um dia, Kahoko conhece Mugino Hajime, um jovem que cresceu em um ambiente completamente oposto ao dela.

Sau khi lớn lên trong sự chiều chuộng và bảo bọc quá mức, Kahoko giờ dấn thân vào vô số trải nghiệm mới khi cô gặp một anh chàng cộc cằn thuộc tầng lớp lao động.
