Daigaku Nyuugakuji kara Uwasa Sareteita Bishoujo San Shimai, Ikiwakareteita Gimai datta.

" Today, I met a nice guy at university.“ ”......What, you, too?" "Wait? Mashiro, too?" Even before school started, Hanamiya, Miyu, and Shinsuino Mashiro came to be known as the “three sisters of beauty.” The girls, who draw attention of everyone around them, had a stepbrother who became separated from them in the past. That's Yuto, whom they meet soon after entering university....... The three girls were just talking about Yuto as a kind person and good brother? Yuto just wants them to treat him normally, but for some reason, all three sisters are making advances on him! "Don't tell the other two......." The first time they reunite in over a decade, the three step-sisters all fall for him, in this harem love comedy. (Source: GA Bunko, translated)
