高瀬 則子

志乃的女儿，主人公的表妹。 白櫻女学院的一年级学生。像母亲一样开朗社交，总是带着笑容的女孩。 仿佛在推内向的主人公一把般，精神饱满地鼓励他。 没有把主人公当作异性看待，而是像兄妹一样对待他。 則子也跟母亲学了钢琴，有相当的水平。

摘自本作简介中该角色的段落

She is Shino's daughter and the protagonist's cousin. She is a first-year student at Shirosakura Jogakuen. Like her mother, she is a cheerful and sociable girl who always has a smile on her face. She cheerfully encourages the introverted protagonist by pushing him along. She does not recognize the main character as the opposite sex, and treats the protagonist as if they were brother and sister. Noriko is also taught piano by her mother and is quite skilled.
