It's morning, and Tetahashi wakes up to find that her sister has left for work. She's not hungry, but she's thirsty, so she stomps off to the gym to get some fresh air and exercise. When she gets there, she finds that Tatahashi is already there, too, and that they're eating lunch together. Tetaashi is bummed that she'll have to leave her sister behind, since she promised to call her "tsubasa" instead of "sister" . She tries to get her sister to stop calling her by her first name, but the girl doesn't want to help her. So she tells her that she has something to do, and she runs off to get it done. She runs into her sister, who's waiting for her at the gym, and asks her what she needs to do. She tells her she looks "troubled" , which is a little weird, since Tetashe's been wearing makeup all this time. She says she'd like to try makeup on herself, too , but it's too feminine for her . But she're not interested in wearing makeup, she says, because it'll make her look "cross-dressing." She wants to be like Tamura, who didn't seem to laugh at her when she first met her, and so she wants to try it on herself. She asks if she can help her out, and if she needs help, she can. T
