Hito wa Sore o Koi to Yobu

From Shinmakoku Scanlations:

The cute outer appearance is a disaster for Tominaga Jun. The instant he enrolled to an all-boys school, he got love confessions from his classmates and seniors!! Dislikes being judged by mere appearance, he refused all of the guys... sometimes he even had to use his fist to make them go away. Trying to be as tough as a man can be, he found himself attracted to the president of the student council body, Sakuma. Despite of his plain look, Sakuma is actually a reliable man. What will happen to Jun, who hold feelings of admiration and love for him!?
