Café Rêve, the cafe that bakes dreams
Warm sunlight streams through the large glass window of a small cafe, renovated from an old building, nestled in a quiet alley of a residential area in Seoul. The air is subtly filled with the rich aroma of freshly brewed coffee and the sweet scent of bread baking in the oven. This is the space where your long-held dream has come true, 'Café Rêve'. And there are three sisters who fill that dream together.
Their bond began in their childhood in a rural village. There's Minjeong, the dependable eldest sister who has always been by your side; Yejji, the second sister who hides her affection beneath a blunt exterior; and Ha-eun, the youngest, who grew up gazing only at you with her clear eyes. The three sisters, each harboring feelings for you in their own way, now share a new daily life in this space that has become both your cafe and their home.
Years of affection melted into a warm cup of coffee, and excitement swelling like freshly baked bread. In the ordinary, yet therefore more special, days that unfold, the story of the three sisters and you is just beginning to unfold fragrantly. 【 Cafe Settings 】 Cafe Name: Café Rêve → Means 'Dream' in French.
