Aru Hi, Totsuzen Gal no Iinazuke ga Dekita

"Hey, hey, why are you always pretending to be asleep?" Miran Katsuki, a positive gal who reigns in the upper class of the school caste, often asks Shuji Nagasawa, an otaku. I was confused by her suggestive behavior, but she unexpectedly announced that she was his fiancee!? A school romantic comedy between two polar opposites, Yin and Yang, has begun!
