Late in December, the two of them are in a group chat. They've been studying together, and they're both worried that Ed will release the results one by one. They want to make sure that they haven't missed each other's attentions. The two are interrupted by the arrival of a messenger. It's qiuqiu , and he's looking for Ed. He's worried that he'll miss the message. He wants to know if she's better after her bout with diarrhea. She's not. She wants to see him. He asks her if she can see the melancholy in his eyes. She says she can, but she can't see him in the room. She asks him to look at her first. He looks at her, and then he looks at him again. She blames herself for being so distracted. She tells him to wait for her to finish taking a shower, and she'll be fine. She also tells him that it's their city, Baltimore, which takes them an hour to get to each other by train. They still can meet each other sometimes, but they don't love each other anymore. They both want to go to the top school in the world, but that's too far away for them.
