冷泉院　雅也

平时就不太表露感情。 在网上评价很高，从名牌大学毕业后， 辗转过几个职业后，作为家庭教师留下了传说般的业绩。 授课费用高昂，根本不是能付得起的金额，但事先没有在网站上记载这一点。 是否接受家庭教师的工作，由雅也和申请者见面后再决定。 无法支付的部分费用用身体支付是规定。

摘自本作简介中该角色的段落

He doesn't usually show his emotions. He has a good reputation online, graduated from a prestigious university, worked in several different jobs, and then made a legendary name for himself as a private tutor. His tuition fees are so high that they are unaffordable, but this is not stated on his website. Masaya decides whether or not to accept a tutoring job after meeting with the prospective student. The rule is that students who cannot afford to pay the fees must pay with their bodies. [Translated from the official site]
