Hiroki wakes up to find Elis sleeping next to him, leading to them having a playful argument. The next day, one of vases is broken and Mami's drawing is ruined. Hiroki immediately suspects Elis, who instantly denies this. She then begins to criticize the art club, and still calls him "onii-chan", leading to Hiroki telling her not to call him that. Hurt, she runs out the room. After inspecting Elis' painting of blue roses, Hiroki asks the art club members if they saw Elis ruin the drawing, or break the vase and after nobody answers him, he concludes that Elis could not have done it.
