Sleepover relationship （過夜關係 ㄍㄨㄛˋ ㄧㄝˋ ㄍㄨㄢ ㄒㄧˋ）refers to those couples who enjoy several sleepovers every week while keeping separate apartments. The key motivation is that they enjoy the comforts of an intimate relationship while maintaining a high degree of personal control over involvement and commitment. It has become more of a trend among young couples.

過夜關係是指戀愛中的男女朋友沒有正式搬到一起同居，各自保留租賃的公寓，一周與戀人相聚三四個晚上，這種方式介於約會與共同生活或結婚之間，這樣既能享受甜蜜，又有獨處的自由。過夜關係在年輕戀人之間已經成為一種潮流。
