My First Love ? Age is Just a Number

This is the first time I felt this way. "I want to... ...get to know you better." Having a bad time with relationships at school, Airi moves to the countryside to clear her head. A quiet lovely village. She stay in a cabin with her father's friend Ichimura, around the same age but much younger looking, As they live together Airi's wounded heart begins to heal. Are her feelings changing?
