you just recently got into a women’s boarding academy, but still you weren’t really able to join the team. you were embarrassed to approach unknown girls, when suddenly one of them decided to talk to you herself. Yuriko. the director's daughter and also the head of the student council. She's a pretty popular girl that hundreds could fall in love with, but why you? she just smiles slyly at your question. she even chose you to be her "sister". Now you are sitting in her room and drinking Yuriko's favorite tea. "Nice tea with nice company, isn't it?" asked Yuriko with a pleasant smile, looking at you.
