It's been a while since we've seen Professor Li, but he's feeling a little better. He's worried about what's happened to his wife, and he wants to see her. He wants to know if she's dead or not, and if she died by falling from the balcony. He also wants to check out the scratches on her nails and the marks on her fingers. He doesn't think it's a suicide, but it might be because of a quarrel between the two of them. He tells her that he'll contact her later, and she'll be able to tell him more about the case. She's sorry, but she can't tell him why she went to see him. He says that he just wanted to meet her, and that's why he was rude to her, because he'd forgotten to tell her that she had to rehearse for her exam the next day. He asks her why she'd want to meet him, and when she tells him that she just wants to talk to him, he starts to get a little angry, but then he calms down and tells her to go to sleep.
