"It's modest, but sensitive." Female lesbian student (double ae) Yukari Ena in school uniform

I love reading and reading with great students, so I have a relationship with my pace. The character is contrasting, but there is only one thing in common. It means that the chest is "A cup". The relationship between the two who knew the facts after they started dating quickly shrinks. One day, there was a situation where the supplementary training related to the summer vacation trip that I had planned before might overlap. Two people who want to go on a trip somehow gather at the house of Ruri and start studying for a follow-up test.
