Summary
While in the middle of chasing a suspect with his captain, Yuri collapses on the ground. After the suspect gets away, the SSS Lieutenant returns to ask what happened, and Yuri says he has caught a cold.

After returning to headquarters to rest, Yuri explains that his immune system breaks down whenever he remembers that Yor is away. Yuri apologizes for letting the suspect escape, but the Lieutenant tells him not to worry and rest up while he gets medication. As he heads out, Yuri asks for a specific brand of herbal tea. As Yuri lies down, he flashes back to a familiar memory of when he was little.

One day, Yuri gets a fever, and Yor wonders what to do. She tries helping him recover but ends up overdoing it, from covering him with numerous blankets, strangling him with green onion, and picking up any healthy things she found outside, to the point of getting stung by bees and slaying a boar. Yuri sees this and vows to grow up healthy and strong, worried for his sister's life.

While Yor brews him tea, Yuri says he is lucky to have a sister like her. Yor says the same and asks Yuri to stay strong and healthy forever. In his thoughts, Yuri desires to make the world a kinder place for Yor's sake. Yor gives Yuri his tea, which he compliments while throwing it up. He then says his body is being affected so strangely that he does not notice his cold anymore, and Yor is happy.

Yuri wakes up in a sweat, and the Lieutenant asks if he is okay. The Lieutenant says he got the herbal tea, which tastes awful, and asks Yuri if he wants it. Yuri says it is the one that works best and tastes most like Yor's brew. After throwing up the tea, Yuri energetically tries to get back to work, but the Lieutenant yells at him to go to bed.
