Kyoutaku-goshi no Kataomoi

Morishita-kun, an ordinary high school student anywhere, has someone he loves. That person is Mr. Sudo, the assistant homeroom teacher. They only see each other at school, he is an adult and a teacher, so it is a love that will never come to fruition...but.... I am happy when I see him, and my heart throbs when I talk to him. But he tries to act normal with his overflowing love in his heart, but...? On the other hand, Sudo-sensei also has a secret that he can't tell anyone...
