I fell in true love in a Boys' Sharehouse that's 99% filled with lies

One day, an innocent university student named Hitomi Akuru, takes part as a substitute for his professor in the "True Lovers Showhouse," a "men's only love reality program." The rules are to live together with other people for one month and, during that time, to find a partner and prove "true love." The winners will get a great prize. There are six participants, including Akuru. When he went to the sharehouse on the day the show begun, he found a lot of good-looking celebrities, among them influencers, actors, and athletes. Moreover, they were all nice in front of the camera, but behind the scenes they were all nasty people with bad personalities! For some reason, Akuru is confused when one of the participants begins making advances on him. But, as he talks to Niwa Kanade, the only actor who doesn't seem to have a secret bad side, he gradually becomes interested in him...! In a show full of lies, will he be able to grasp the meaning of true love?
