　　經由不求回報的愛，而逐漸成長的妹妹燈兒；與無法割捨家人羈絆，拙於處理感情的姊姊花兒，兩人價值觀、結婚觀、人生觀完全迥異，她們是否能在大自然的守護下，藉著戀愛找到屬於自己的幸福呢？

The older sister who had set backs in Tokyo, and her younger sister who wants nothing more than to move there. The two sisters, who were born and raised in a teahouse called Juicchome Chaya halfway up Mt. Takao on the outskirts of Tokyo, seek for happiness while living in a beautiful natural setting and experiencing different love affairs in this pure and heartfelt story. But one thing they can't get around in their search for happiness is the family. First there's the father, a pigheaded guy with an artisan spirit who pushes his weight around as father, and then the mother who's a tricky customer in her own right. And it's not only the family, the whole village seems to be following the love complications of our two heroines with bated breath and spreading the word around.
