In "The Case of Ritsu Onodera No.16," Ritsu collapses from the stress of overwork and self-neglect. Isaka takes him to the hospital and calls Takano, and the two discuss Ritsu's family and the expectations on him. Takano inspects Ritsu's food-less fridge and insists on taking charge of his nutrition. They discuss Ritsu's overwork and his eagerness to improve. When Takano starts to leave, Ritsu grabs onto him to stay. They get intimate, and Ritsu passes out immediately after. On Monday, Emerald finishes moving to their new office, and Takano complains that he's cleaning up again because he spent the weekend cleaning Ritsu's messy apartment, announcing to the department that he did it out of "love," to Ritsu's embarrassment.
In "The Case of Ritsu Onodera No.17," Takano is insistent on keeping track of Ritsu's nutrition, and Ritsu runs into Haitani which causes tension with Takano. After another stressful work day, Takano insists on dinner, which Ritsu declines. On his way home, Ritsu runs into Haitani who's kissing another guy, and Haitani offers to "buy his silence" by taking him to dinner. The two discuss Takano's work for Weekly Earth. Takano learns that Ritsu was with Haitani and gets jealous, and the two talk about their relationship, with Ritsu frustrated that Takano doesn't listen to him and that they're going about a relationship out of order. Takano offers to make some changes and confesses to Ritsu again.
