Candied Maid Cafe

My two sisters and I own a cafe on top of a hill. I'm the patissiere. I always ask Rei Yuuki, a regular who's three years younger than me, for feedback on my latest creations. He swears like a sailor, but... gives the best feedback a girl could ask for. Then again, he's so popular with other girls that everyone calls him "prince." I don't think he'd be interested in an older girl like me...
