From Chibi Manga:
I have thought that “being alone is easier and more fun”. The romance comedy between the worst combination, begins! Arisu Tobe, the vice chairman of the student organization at Margarito Institute, a girls’ school for junior and senior high schools, hates men. She couldn’t keep up with her surroundings during the annual joint cultural festival with the affiliated boys’ school, and when she met Bene, the vice chairman of the student organization at Kigiku High, they just quarreled … But one day, she heard from Bene’s close friends that “he likes her”!?
