Atataka na Hari

I've fallen in love with my teacher... Ryoutarou is a member of his high school's knitting club and he is in love with a woman that he had met by accident. It turns out that that woman is actually a teacher at his school. His "younger sister", Yuiko watches over his romance with complicated feelings while Miki-sensei, the person Ryoutarou is in love with, has a secret she is hiding... Thus, their various "first love" begin to become entangled with each other's.
