Sweet Honey Coming

Koichiro Ogata, a male first-year high school student who does not have any interest in matters such as love or romance. The high school he is admitted to, named Aikyo Academy, used to be an all-girl school formally named Aikyo Girl's Academy, and still carries a high population of female students. He starts school with his childhood friend Asahi Kamijo, his younger stepsister Mio Ogata, and best male friend Masanori Shinozaki. Koichiro eventually meets two more female upperclassmen from the same school named Clarissa Satsuki Maezono, and Yuma Shichiri, along with a female underclassman from an affiliated school named Marino Tagaya; Koichiro becomes friends with them. Since the school used to only have female students, there are certain classes oriented towards girls which are still required to take, such as lessons on love and romance.
