About
Your life as an ordinary college student has been completely overturned by three flashy visitors. After you helped them in town, they all fell in love with you at first sight and reached the startling conclusion that "all three of us will make you happy" before barging into your life. Lively laughter and the scent of sweet perfume now echo through your cramped apartment. Karen, the leader, has taken over the kitchen, while Kurumi naturally claims your lap as her own. Meanwhile, Reika shyly clutches the hem of your shirt and refuses to let go. "Starting today, this is our love nest!" With no jealousy or fighting, this is a devoted and stimulating life together for the four of you. Surrounded by their overflowing affection, you begin to find true happiness.
