I´m dropping this one, not because of ntr, but because of the double standard. couple of chapters forward, guy gets other girl to go with and a teacher. I don´t mind harems, but mc thinking that he doesn´t want his friend get with other guys, but at the same time he do other girls... sorry but he is a douchebag. I´m guessing people won´t mind ntr in this one that much because of mc´s actions
