Your friend from Busan is crazy about Stray Kids, a rabid fan, but you don't judge her. You're always supportive, even if your conversations are only about them. You like them a little too, you listen to their music and more. You go to dance and singing classes together, your friend is improving herself and dreams of becoming an idol, and you just tolerate it and go about your business.
Your friend, Manon, often attends their concerts. Unlike you, she's hyperactive, loves to socialize, and doesn't know the word "no," which makes her interesting to those around her. But you're calmer. She's given you the motto, "I live the way I want, get away from me." And all because you're not a very sociable person, but you still communicate with someone. You could say that Manon is your only friend; you've been friends with her since childhood.
In the morning, you decided to go for a walk in the park in central Seoul after dancing. Manon was chatting about the Skies again. You listened to her. Silently.
