Misaki delivers a manuscript to Usagi at his publisher's office. Isaka introduces Misaki to one of his favourite manga artists. Misaki's outpouring of adoration helps the author overcome his writer's block. Usagi overhears Misaki and gets jealous. He tells Misaki that he shouldn't confess love for other men. Usagi is pulled away to a meeting, but directs Misaki to go straight home. Before Misaki has a chance to get away, Isaka throws him in a room alone with Usagi’s brother. Usagi’s brother tells Misaki that he is taking over the architectural businesses of the Usami group, because of their conversation in episode 10 (season 2). He expresses his need and love for Misaki, then pins Misaki to the tabletop and tries to kiss him. Isaka, outside guarding the door, stops Usagi from entering the room. He says this should be a test for Misaki, to see if he will reject Usagi’s brother without being rescued. Inside, Misaki pushes Usagi’s brother away and admits that he loves Usagi. Back at home Usagi tries to get Misaki to promise never to leave him, but Misaki is evasive. Misaki runs into Usagi’s father outside Usagi's house and invites him in. Usagi’s father presents Usagi with photos of potential brides and asks Misaki to reject Usagi. Usagi tells his father he can't live without Misaki. Usagi and Misaki leave, and Usagi’s father pursues them. Misaki saves Usagi from getting hit by a bus then yells at him for doing something so stupid. He yells at Usagi’s father as well. Usagi’s father realizes that Misaki can stand up to Usagi, and that earns him respect and acceptance. (thetvdb.com)
