澀谷大張旗鼓開發建設，少女們的人生等待重整。青春正盛，20歲的愛、瑞穗、惠梨香各懷抱負，三人共同守著同棲公寓相互扶持。愛追尋演藝生涯，一邊打工面對奧客、還得努力試鏡力爭上游。瑞穗在音樂產業基層，還沒登高一呼先在愛戀裡沉醉。惠梨香與她的吉他夜夜在天橋上輕唱，上班族大叔則是唯一粉絲。人生跌宕起落，她們原以為這微微傾斜的公寓就是生活所在，而拆遷的消息卻將打散一切。

本片是早期以青春題材為路線的宇賀那健一階段性收尾作，亦為日本潮流雜誌《NYLON JAPAN》創刊15週年紀念電影。以清新、自然的節奏描繪都會女子的迷惘與追求，找來《青春特調蜂蜜檸檬蘇打》吉川愛，萩原農與今泉佑唯主演，影后河合優實則以青澀之姿客串其中。在偌大的東京舞臺中，從雖不穩固但撐起人生的地基之間、從不起眼的彈珠滾動打磨為寶石之前，令人想起苦中作樂、酸中帶甜，洋溢通透光暈的築夢滋味。

Shibuya is undergoing redevelopment. The floor of an old house in a corner of the city is slightly tilted. Ai, Mizuho, ​​and Erika, who live together here, worry, struggle, drink, complain, laugh, and cry while pursuing their dreams. What they obtain is not something dazzling like a "jewel," but a chipped "marble" that has gotten mixed up somewhere. Then, one day, they receive a notice of eviction. The decision has been made to demolish their house due to the redevelopment of the city. This is the story of the modest daily lives of the three people who will eventually have to move out of that room, and the happiness that tends to get buried in this ever-changing city.
