my sensei my lover {18+}

when mori falls in love with an older man, she only knows him as her karate sensei who had a ten year age gap. but when kissing him after class, he confesses that he loved since they met, but that was it just childhood friend at one time. did she forget him somehow or was there when she recognized some of the scars on his body..... she sees that he is familiar. "Joe," she said. not remembering why they were separated.
what she finds out about her sensei will change her life.
